Collections management involves the development, storage, and preservation of cultural property, as well as objects of contemporary culture (including contemporary art, literature, technology, and documents) in museums, libraries, archives and private collections. The primary goal of collections management is to meet the needs of the individual collector or collecting institution's mission statement [ further explanation needed ], while also ensuring the long-term safety and sustainability of the cultural objects within the collector's care. Collections management, which consists primarily of the administrative responsibilities associated with collection development, is closely related to collections care, which is the physical preservation of cultural heritage. The professionals most influenced by collections management include collection managers, registrars, and archivists.
Cultural property collections require a great deal of care and protection in order to ensure their safety from external loss or damage, but they also require in-depth documentation to assist in tracking the life of the object within the holding institution. To accommodate these needs, collectors adhere to collections management and collections care standards and practices, which serve to create a safe environment for collection objects with clear and precise accompanying documentation. Where collections care addresses the physical actions necessary to prevent or delay damages of cultural heritage, collection management can be defined as "a process of information gathering, communication, coordination, policy formulation, evaluation, and planning." [1] These processes influence decisions about records management and the collections management policy, which outlines protocols for the collection scope, collections care, and emergency planning and response.
Collection management systems (CMS) are software programs designed to aid in the archiving and cataloging of objects in a collection. Within libraries, archives, and museums. Although every CMS program is unique, there are several features that are considered standard:
According to the Smithsonian Institution, a record is "any official, recorded information, regardless of medium or characteristics which are created, received, and maintained" by an individual collector or institution. [3] As every object within a collection must have accompanying documentation, records management functions as the primary focus of collections management, and covers a wide range of documentation and policy standards. Topics covered under the umbrella of records management include collection information management systems, collections accession and deaccession policies, collection management policies, cataloging, and curation. The lack of appropriate record-keeping systems in museums compromises the security of museum collections and threatens the role of museums as information centers. Planned and systematized management of records improves programs and activities in museums, thereby leading to effective governance and operation of the museum. [4]
Cataloging is the process of entering informational data about an object into a collection catalog or database. This process involves assigning unique identification numbers to individual objects within a collection, and attaching relevant accompanying documentation to the item such as curatorial worksheets, photographs, condition assessments, and accession and/or deaccession information. [5] A catalog is meant to serve as a systematic written or digital record of every object within a collection, and should at the very least, include an object description that will allow for easy identification of an object. [6]
Cataloging is an important aspect of collections management as it provides the individual records associated with each object within a collection. Should an object be lost or destroyed, the catalog entry can be utilized as a permanent record of the object and its data. For some collections, such as natural history collections, the catalog entry for an object or specimen also contains the scientific values and research information about the physical object, making maintenance of a catalog entry imperative for future research and education. [5] Most modern collectors and institutions utilize CMS to streamline the catalog process. For this to be effective, data entry standards must be utilized for data structure, data values, and data content, which then "form the basis for a set of tools that can lead to good descriptive cataloguing, consistent documentation, shared records, and increased end-user access." [7]
Curation can be defined as the collecting, organizing, preserving, and displaying of information about a specific object or collection topic. The role of curating is performed by individuals known as curators, who, in many cases, are trained as subject specialists. Curators conduct research on objects, offer guidance in the organization of a collection, and select objects to be utilized in exhibitions. [8] Curation involves the development and design of exhibitions, typically based on objects within the collection, as well as the in-depth research and writing of materials associated with the collection. [9]
Digital curation is an extension of content curation, and involves the collecting, preserving, and archiving of digital assets associated with digitized collections. [10] [11] Digital assets include both those items that originated in a digital form and are considered born-digital (i.e. websites, wikis, and digitally created sound and photographs), as well as analog items that have been digitized (i.e. cataloged in digital form, while still maintaining the original physical/analog form). [12] [13] Digital curation, like content curation, also involves the development and design of exhibitions based on objects within the collection, which in this case, often involves website maintenance for online exhibits.
Whether born-digital or digitized, many modern collections contain some form of digital collection content which must be maintained in much the same way as physical objects. Preservation of digital assets involves the creation of metadata to improve accessibility and object tracking, preventing technical obsolescence and data loss due to mismanagement, performing routine audits of technical software and digital catalogs to ensure data remains uncorrupted, applying authorization standards to protect data from unauthorized alterations, and managing content for the purposes of research and exhibition. [14]
A collection management policy lays the foundation for how an institution handles situations pertaining to their collection. It can be defined as "a detailed written statement that explains why an institution is in operation and how it goes about its business. The policy articulates the institution's professional standards regarding the items left in its care and serves as a guide for the staff". Since institutions are often faced with questions that deal with what objects they should acquire, how to handle removing or loaning items in the collection, or standards of care for items; it is imperative to have a well-written policy that can help prevent possible issues on the institution's end. Prevention is the best approach when dealing with operations and objects in the collection, therefore the policy is an important document that can be looked at almost like boundaries set in place to help insure that the museum stays true to its mission while also providing the best care for the collection.
The primary focus of collections management is to document the standards and practices necessary to develop, care for, and make available for use, the collection objects within a collector or institution's care. To accomplish this, a collections management policy is created in which detailed information is provided to explain the specific needs of the collection based on type, age, location, etc. Collection management policies are specific to the collection-holding institution and these policies lay out terms such as which personnel are responsible for individual tasks involving the collection, if and when an object should be acquired for or removed from the collection, who within the institution has access to the collection, and the preventive care needs of each object within the collection. [15]
Given that almost every decision a museum makes is done with its mission statement in mind, it is important that it is included in the policy. A mission statement addresses the museum's focus in terms of its purpose and its roles and responsibilities to the public and collections. This statement is what helps determine everything the museum does and should be referenced to on a regular basis to ensure that decisions are still in line with the museum's original goal. Museum mission statements should adhere to the standards of the American Alliance of Museums. [16]
In addition to the mission statement, policies typically include a section that outlines the scope of the collection. This is a useful part of the policy that "reviews the history of the collection; considers its strengths, weaknesses, and current uses; and states what the museum does and does not collect" . The collections policy or selection criteria of a library, archive or museum collection is a statement of the institution's priorities as they apply to the acquisition of new materials. Collections policies guide the process of collection development.
Even the largest, best funded and most famous libraries (such as the Library of Congress, the British Library and Stanford University) cannot acquire, house, catalogue and maintain all works, [17] so a policy or set of criteria is required for selecting which should be acquired. Generally collections policy is related to the mission or purpose of the library: for example national libraries collect materials related to that nation or published in that nation's territory, academic libraries generally collect materials used in teaching and research at the institution which they serve [18] and public libraries collect materials which are expected to satisfy demands from the public they serve.
Sample collections policies include:
As well as setting priorities for purchasing materials, collections policies also serve as a guide when libraries are offered gifts of materials or endowments. Acquisition of materials can be less costly than the processing (sorting, cataloguing, etc.) and long-term storage costs of many materials, and even free gifts to libraries usually have associated costs.
An institutions's policy may also look to include a history of the institution.
In addition to general care standards, a collection management policy is also governed by the local and international legal restrictions placed on certain cultural heritage objects and the management needs associated with them. There are countless laws on the books that specify how antiquities, archaeological findings, and ethnic pieces must be handled and maintained to ensure their physical safety as well as the ethical considerations that these unique collection objects must address.
Examples of local laws within the United States of America include:
Examples of international legislation include:
Written as a subsection of the overarching collection management policy, most collectors and cultural institutions utilize a collections policy, or selection criteria policy, in which it is outlined what purpose the collection serves, and the types of objects that are considered most relevant. The collection policy lays out the scope of the collection and its relevance to the institution's mission statement by serving as "a broad description of the [institution's] collections and an explanation of how and what the museum collects and how those collections are used." [29] The scope of the collection as laid on it in this policy serves to define if, when, and how a cultural institution chooses to accession or deaccession objects from its collection. Additionally, as different types of collections require unique care protocols, the collection policy also details the categories associated with the collection such as library or archive, education or research, permanent, and exhibit. The collection policy might also address conflicts of interest for employees who hold personal collections that are similar to those of the institution within which they are employed. [15] [29]
Accessioning can be defined as "the process of creating a permanent record of an object, assemblage, or lot received from one source at one time for which the [institution] has custody, right, or title, and assigning a unique control number to said object, assembly, or lot." [30] As part of the collection scope policy, collectors and institutions must lay out acquisition terms to ensure only relevant objects are successfully accessioned into the collection. This portion of the policy discusses: who within the institution is authorized to make decisions on whether an object is acquired or not, under what legal terms the object is to be acquired (i.e. documentation proving legal purchase, import and export restrictions, and intellectual property rights), and repository agreement information if the object is to be stored within an offsite facility. [15] The accessioning section of the collection policy might also discuss the strengths and weaknesses of the collection by examining the history of the collection as a whole. This in turn allows the collector or institution to set guidelines for improving, growing, and developing the collection in a way that is of most benefit. [29]
Deaccessioning is the opposite of accessioning and involves the permanent removal of an object and all associated records from a collector's or institution's collection. Like the accession portion of the collection policy, the deaccession section lays out the terms under which an object may be considered for removal, as well as the individuals with the authority to approve the process. Additionally, this section lays out the legal restrictions associated with removal of the object, and the types of disposal that are appropriate based on the reason for the deaccession. [15] There are many reasons that an object may be removed from a collection including:
Collectors and collecting institutions sometimes transfer objects to or from their collections for temporary periods of time as part of loan or temporary custody agreements. These loans help share and disseminate information to different communities and can prove mutually beneficial to both collection-holding individuals or institutions. [29] Loans can occur for a variety of reasons and for policy purposes loans may be defined as: stationary or traveling exhibition loans, exchange loans, study loans, promised gifts, fractional-interest gifts (a "donor's remaining interest in a partial gift"), and long-term loans. The policies for loans may also be applied to acquisitions during the processing period, unsolicited objects until a return can be arranged, and collection objects or those objects found, abandoned, or unclaimed, in which ownership is unclear. [29] [32]
Within the collections scope section of a collections management policy, there is typically an area dedicated to discussing the procedures for loan approval and acceptance, associated acquisition fees, required documentation, specific insurance requirements, and monitoring instructions for the temporary holdings. This section may also include information about old loans and works with restrictions governing if and when they are allowed to leave the holding-institution. [29] The loan policy should address both incoming and outgoing loans with thoroughly explained written procedures. [32]
Collections management focuses heavily on planning and response standards, and lays out these practices in documents detailing how staff responsible for the care of a collection should address the various hazards for the collection. [33] A risk management plan or risk mitigation strategy is the section of the policy identifying potential hazards for the collection based on the region in which the collection is located, including fires, earthquakes, criminal activity, or flooding, in addition to damages from repairs, building failure, improper collections care, and neglect. [34] To inform risk management plans, a significance assessment and a risk assessment or a collection condition assessment is conducted. [35] [36] [37]
Collections care can be defined as the physical preventive care measures taken to prevent damage or delay the natural deterioration of cultural heritage collection objects. These practices strive to provide enhanced safety for collections by minimizing damages from external sources such as improper handling, vandalism, climate changes, overexposure to light, and pests. [38] A collections management policy carefully examines the preventive conservation needs of the individual objects within the collection, in order to provide practices and standards for how to mitigate threats, as well as the proper procedures for addressing issues as they arise. Sub-topics within this section may include display and storage housing, packing and transport, and integrated pest management.
When objects are held within a collection, either in storage or on display in an exhibit, the primary concern should be on the continued safety of the collection. To accomplish this, the collector or holding-institution must take into consideration proper housing containers, as well as environmental conditions necessary to prevent damages. The collections management policy for the collection should contain sections in which display and storage housing needs for the objects are addressed in full. Consultation with a conservator-restorer may be necessary to fully address these topics.
In terms of housing, solid structural design is vital in ensuring objects remain undamaged while stationary. This includes accounting for padding and support of the objects to prevent damage from bumps and snags, and stable display cases or mounts, which often requires collaboration with a mount maker to ensure proper creation and installation. Stands, shelves, drawers, and cases, in addition to fasteners, adhesives, papers, and foams, must all be chosen based on their compatibility with the structural design and materials of each individual object. [39] The collections management policy should outline housing specifications such as the use of acid-free (pH neutral) and dye-free materials; types of enclosed cabinetry where available; appropriate coverings such as fabrics (e.g. unbleached muslin), polyethylene sheeting, and closed-cell foam (e.g. Ethafoam); containers made of paper, plastic, wood, or metal; enclosures such as folders or mats; and standards for frames, supports, and mounts. [40]
The main environmental conditions that require outlined protocols in the collections management policy include temperature, relative humidity (RH), light, and contaminants. [41] It is impossible to completely prevent natural deterioration of objects, but by carefully monitoring and implementing policies regarding environmental conditions, the effects of these conditions can be greatly reduced.
Objects within a collection should ideally, be handled as little as possible since every time they are handled, they are at an increased risk of damage. Proper display and storage housing will help to mitigate some of the risks of accidental damage, but it is important to create and implement high standards for the routine care and handling, as well as the packing and transporting, of collection objects. [48] It is extremely important to ensure that staff are aware of and educated on standard practices for handling objects such as hand washing protocols, the appropriate use of cotton or latex gloves, established practices for identifying structural weaknesses that may require special care, and the accepted modes of transportation of objects within the holding-institution (i.e. flatbeds, carts, tote pans, pads, and tissue papers). [49]
Sometimes a collector or institution will have a need to move objects outside of exhibit and storage locations. The collection management policy, which discusses the proper procedures for loans and acquisitions, must therefore also address proper packing and transport protocols to ensure that the objects arrive at their destination safely. To ensure safe transport, safe handling techniques must be combined with individual packing requirements for the specific object being shipped. Ideally, the object will be packaged in a shipping container that provides protection from shock, vibration, sudden climate changes, and mishandling. Collection management policies will advise staff on how best to address issues such as "the object's fragility, the shipping method, the climate through which the objects will travel, and the climate at the object's destination." [48] During the packing and transport process, it is likely that several departments within the shipping institution may contribute, and collaboration with the receiving institution must be arranged to provide policies for acclimatization and unpacking of the object once received. [50] [51]
Within the collections care section of a collections management policy, there is typically a section dedicated to integrated pest management (IPM). This section covers the policies related to the prevention and suppression methods of various types of pests typically found within collections. IPM focuses on utilizing non-pesticide prevention and treatment techniques in order to minimize health risks for personnel as well as damages to the collection itself. Examples of types of pests that should be addressed include "insects, mold, mice, rats, birds, and bats." [52]
The collection management aspect of IPM involves creating and implementing policies for the routine inspection of objects and housing facilities, authorized trapping procedures, and documentation of all inspections or trapping programs utilized within the facility. These policies are called cultural controls, and the physical techniques utilized as part of the collections care are known as mechanical controls. [52] Specific cultural controls that may be documented within the collections management policy include:
Physical security systems for protected facilities are generally intended to: [53] [54] [55]
It is up to security designers, architects and analysts to balance security controls against risks, taking into account the costs of specifying, developing, testing, implementing, using, managing, monitoring and maintaining the controls, along with broader issues such as aesthetics, human rights, health and safety, and societal norms or conventions.
Created in conjunction with the collection management policy, most collecting institutions will also possess a disaster preparedness and emergency response policy that outlines what procedures should be taken to prevent injury or loss of life for all personnel and building visitors, as well as how to minimize damages or loss to the collection. [33] The plan should outline protocols for how to handle a disaster, starting with the chain of command within the emergency response team, as well as the individual responsibilities of each member of the staff. The emergency response team will include a managing official responsible for notifying other members of the team of a disaster and overseeing the implementation of the emergency response tasks. These staff members are typically trained in proper collection handling protocols. The disaster preparedness and emergency response plan should also include detailed instructions explaining how each type of disaster should be handled including the initial threat assessment and response, evacuation procedures where appropriate, damage mitigation plans, salvage priorities, and post-damage inventories and recovery procedures. [56] [57]
Sustainability is defined as the use, development and protection of resources to meet both current and future generation needs. [58] Collection sustainability policies are collection or institution specific, as they balance the collections economic and social context against the collections environmental impact, while ensuring compliance with local and national legislation. A sustainability action plan is used to identify unsustainable practices, outline a target goal and completion timeframe, and assign responsibilities. Sustainability policies and sustainability action plans consider sustainability through the lens of; economic resource use, when considering cost-benefit of collection storage, staffing, procurement, maintenance and waste processes; [59] social capital, when ensuring representational parity through community engagement and advocacy of stakeholders; [60] and environmental impact, when emphasizing waste reduction, life cycle assessments and environmentally safer alternatives to conservation chemicals, packaging and transport materials. [61]
Sample sustainability policies include:
The conservation and restoration of cultural property focuses on protection and care of cultural property, including artworks, architecture, archaeology, and museum collections. Conservation activities include preventive conservation, examination, documentation, research, treatment, and education. This field is closely allied with conservation science, curators and registrars.
A curator is a manager or overseer. When working with cultural organizations, a curator is typically a "collections curator" or an "exhibitions curator", and has multifaceted tasks dependent on the particular institution and its mission. The term "curator" may designate the head of any given division, not limited to museums. Curator roles include "community curators", "literary curators", "digital curators" and "biocurators".
A museum is distinguished by a collection of often unique objects that forms the core of its activities for exhibitions, education, research, etc. This differentiates it from an archive or library, where the contents may be more paper-based, replaceable and less exhibition oriented, or a private collection of art formed by an individual, family or institution that may grant no public access. A museum normally has a collecting policy for new acquisitions, so only objects in certain categories and of a certain quality are accepted into the collection. The process by which an object is formally included in the collection is called accessioning and each object is given a unique accession number.
In conservation, library and archival science, preservation is a set of preventive conservation activities aimed at prolonging the life of a record, book, or object while making as few changes as possible. Preservation activities vary widely and may include monitoring the condition of items, maintaining the temperature and humidity in collection storage areas, writing a plan in case of emergencies, digitizing items, writing relevant metadata, and increasing accessibility. Preservation, in this definition, is practiced in a library or an archive by a conservator, librarian, archivist, or other professional when they perceive a collection or record is in need of maintenance.
Conservation and restoration of movable cultural property is a term used to denote the conservation of movable cultural property items in libraries, archives, museums and private collections. Conservation encompasses all the actions taken toward the long-term preservation of cultural heritage. Activities include examination, documentation, treatment, and preventive care, which is supported by research and education. Object conservation is specifically the actions taken to preserve and restore cultural objects. The objects span a wide range of materials from a variety of cultures, time periods, and functions. Object conservation can be applied to both art objects and artifacts. Conservation practice aims to prevent damage from occurring, a process known as 'preventive conservation'. The purpose of preventive conservation is to maintain, and where possible enhance, the condition of an object, as well as managing deterioration risks, such as handling and environmental conditions. Historically, object conservation was focused on the category of fine arts but now many different types of objects are conserved. Each type of object material, typically denoted by organic or inorganic then the specific medium, requires a specialized professional conservator and often requires collaborative work between museum staff, scientists, and conservators.
Sustainable Archaeology (SA) is a digital archaeological research facility and collections repository that advances a sustainable form of practice and research archaeology in Ontario. Sustainable Archaeology is an inter-institutional collaborative research facility between the University of Western Ontario (Western) and McMaster University.
Collection maintenance is an area of collections management that consists of the day-to-day hands on care of collections and cultural heritage. The primary goal of collections maintenance or preventive conservation is to prevent further decay of cultural heritage by ensuring proper storage and upkeep including performing regular housekeeping of the spaces and objects and monitoring and controlling storage and gallery environments. Collections maintenance is part of the risk management field of collections management. The professionals most involved with collections maintenance include collection managers, registrars, and archivists, depending on the size and scope of the institution. Collections maintenance takes place in two primary areas of the museum: storage areas and display areas.
A collection manager ensures the proper care and preservation of objects within cultural institutions such as museums, libraries, and archives. Collection managers, along with registrars, curators, and conservators, play an important role in collections care. Collection Managers and Registrars are two distinct collection roles that are often combined into one within small to mid-size cultural institutions. Collection Managers can be found in large museums and those with a history and natural history focus whose diverse collections require experienced assessment to properly sort, catalog, and store artifacts. A collection manager may oversee the registrar, archivist, curator, photographer, or other collection professionals, and may assume the responsibilities of these roles in their absence within an organization.
A paintings conservator is an individual responsible for protecting cultural heritage in the form of painted works of art. These individuals are most often under the employ of museums, conservation centers, or other cultural institutions. They oversee the physical care of collections, and are trained in chemistry and practical application of techniques for repairing and restoring paintings.
A mount maker is responsible for the creation of structures called object mounts used to provide unobtrusive physical support, stability, and security of objects while on display, in storage, or being transported to museums, art galleries, libraries, archives, botanical gardens or other cultural institutions. Protection and long-term conservation of the object is a key goal of mount makers. This is accomplished through careful design, selection of materials and manufacturing process that will not inadvertently harm the object, and a cautious installation process of the object into its place in an exhibit. Professionals in this field can be employed directly by an institution, be independent contractors, or work as part of larger cultural institution exhibit design firms.
A museum/library/archival registrar is responsible for implementing policies and procedures that relate to caring for collections of cultural institutions like archives, libraries, and museums. These policies are found in the museum's collections policy, the guiding tenet of the museum explaining why the institution is in operation, dictating the museum's professional standards regarding the objects left in its care. Registrars focus on sections that include acquisitions, loans, exhibitions, deaccessions, storage, packing and shipping, security of objects in transit, insurance policies, and risk management.
Disaster preparedness in museums, galleries, libraries, archives and private collections, involves any actions taken to plan for, prevent, respond or recover from natural disasters and other events that can cause damage or loss to cultural property. 'Disasters' in this context may include large-scale natural events such as earthquakes, flooding or bushfire, as well as human-caused events such as theft and vandalism. Increasingly, anthropogenic climate change is a factor in cultural heritage disaster planning, due to rising sea levels, changes in rainfall patterns, warming average temperatures, and more frequent extreme weather events.
The conservation and restoration of time-based media art is the practice of preserving time-based works of art. Preserving time-based media is a complex undertaking within the field of conservation that requires an understanding of both physical and digital conservation methods. It is the job of the conservator to evaluate possible changes made to the artwork over time. These changes could include short, medium, and long-term effects caused by the environment, exhibition-design, technicians, preferences, or technological development. The approach to each work is determined through various conservation and preservation strategies, continuous education and training, and resources available from institutions and organization across the globe.
The documentation of cultural property is a critical aspect of collections care. As stewards of cultural property, museums collect and preserve not only objects but the research and documentation connected to those objects, in order to more effectively care for them. Documenting cultural heritage is a collaborative effort. Essentially, registrars, collection managers, conservators, and curators all contribute to the task of recording and preserving information regarding collections. There are two main types of documentation museums are responsible for: records generated in the registration process—accessions, loans, inventories, etc. and information regarding research on objects and their historical significance. Properly maintaining both types of documentation is vital to preserving cultural heritage.
A textile conservator is a conservator-restorer charged with the care, treatment, research, and preservation of textiles. Issues addressed by a textile conservator are generally related to the field of textile preservation, and include damage caused to textiles by: light, mold and mildew, insects, cleaning, surface cleaning, washing, mounting for display, and storage. Variations in textile types and “the diversity of the textile conservator’s work makes it a very rewarding profession”. Textiles are among the most fragile artifacts, as they are susceptible to damage from atmospheric pollutants, moisture, biological organisms, and environmental changes and care varies with size, shape, material, and condition issues, all of which a textile conservator must be well versed.
A Collections Management System (CMS), sometimes called a Collections Information System, is software used by the collections staff of a collecting institution or by individual private collectors and collecting hobbyists or enthusiasts. Collecting institutions are primarily museums and archives and cover a very broad range from huge, international institutions, to very small or niche-specialty institutions such as local historical museums and preservation societies. Secondarily, libraries and galleries are also collecting institutions. Collections Management Systems (CMSs) allow individuals or collecting institutions to organize, control, and manage their collections' objects by “tracking all information related to and about” those objects. In larger institutions, the CMS may be used by collections staff such as registrars, collections managers, and curators to record information such as object locations, provenance, curatorial information, conservation reports, professional appraisals, and exhibition histories. All of this recorded information is then also accessed and used by other institutional departments such as “education, membership, accounting, and administration."
The conservation and restoration of human remains involves the long-term preservation and care of human remains in various forms which exist within museum collections. This category can include bones and soft tissues as well as ashes, hair, and teeth. Given the organic nature of the human body, special steps must be taken to halt the deterioration process and maintain the integrity of the remains in their current state. These types of museum artifacts have great merit as tools for education and scientific research, yet also have unique challenges from a cultural and ethical standpoint. Conservation of human remains within museum collections is most often undertaken by a conservator-restorer or archaeologist. Other specialists related to this area of conservation include osteologists and taxidermists.
Deaccessioning is the process by which a work of art or other object is permanently removed from a museum's collection to sell it or otherwise dispose of it.
The exhibition of cultural property is a practice used by organizations where collected objects are put on display to the public. The objects are carefully chosen and placed together to offer educational value, and often to tell a story.
The 'ten agents of deterioration' are a conceptual framework developed by the Canadian Conservation Institute (CCI) used to categorise the major causes of change, loss or damage to cultural heritage objects. Also referred to as the 'agents of change', the framework was first developed in the late 1980s and early 1990s. The defined agents reflect and systematise the main chemical and physical deterioration pathways to which most physical material is subject. They are a major influence on the applied practice of conservation, restoration, and collection management, finding particular use in risk management for cultural heritage collections.
