This page is a glossary of library and information science.
A librarian is a person who works professionally in a library providing access to information, and sometimes social or technical programming, or instruction on information literacy to users.
The five laws of library science is a theory that S. R. Ranganathan proposed in 1931, detailing the principles of operating a library system. Many librarians from around the world accept the laws as the foundations of their philosophy.
Digitization is the process of converting information into a digital format. The result is the representation of an object, image, sound, document, or signal obtained by generating a series of numbers that describe a discrete set of points or samples. The result is called digital representation or, more specifically, a digital image, for the object, and digital form, for the signal. In modern practice, the digitized data is in the form of binary numbers, which facilitates processing by digital computers and other operations, but digitizing simply means "the conversion of analog source material into a numerical format"; the decimal or any other number system can be used instead.
A research library is a library that contains an in-depth collection of material on one or several subjects. A research library will generally include an in-depth selection of materials on a particular topic or set of topics and contain primary sources as well as secondary sources. Research libraries are established to meet research needs and, as such, are stocked with authentic materials with quality content. Research libraries are typically attached to academic or research institutions that specialize in that topic and serve members of that institution. Large university libraries are considered research libraries, and often contain many specialized branch research libraries. The libraries provide research materials for students and staff of these organizations to use and can also publish and carry literature produced by these institutions and make them available to others. Research libraries could also be accessible to members of the public who wish to gain in-depth knowledge on that particular topic.
Hybrid library is a term used by librarians to describe libraries containing a mix of traditional print library resources and the growing number of electronic resources.
A teacher-librarian or school librarian or school library media specialist (SLMS) is a certified librarian who also has training in teaching.
Library collection development is the process of systematically building the collection of a particular library to meet the information needs of the library users in a timely and economical manner using information resources locally held as well as resources from other organizations. "According to is a dynamic self perpetuation cycle or process and consists six definable stages namely,community analysis, selection policies, selection, acquisition, weeding and evaluation.
A school library is a library within a school where students, staff, and often, parents of a public or private school have access to a variety of resources. The goal of the school library media center is to ensure that all members of the school community have equitable access "to books and reading, to information, and to information technology." A school library media center "uses all types of media... is automated, and utilizes the Internet [as well as books] for information gathering." School libraries are distinct from public libraries because they serve as "learner-oriented laboratories which support, extend, and individualize the school's curriculum... A school library serves as the center and coordinating agency for all material used in the school."
The State Library of North Carolina is an institution which serves North Carolina libraries, state government employees, genealogists, and the citizens of North Carolina. The library is the main depository for North Carolina state publications and serves the needs of North Carolina government agencies and state government employees by providing access to information resources that are vital to public decision-making and economic development.
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.
A special library is a library that provides specialized information resources on a particular subject, serves a specialized and limited clientele, and delivers specialized services to that clientele. Special libraries include corporate libraries, government libraries, law libraries, medical libraries, museum libraries, news libraries. Special libraries also exist within academic institutions. These libraries are included as special libraries because they are often funded separately from the rest of the university and they serve a targeted group of users.
Preservation survey is the process of collecting and analyzing data about the physical condition of library materials.
A digital library is an online database of digital objects that can include text, still images, audio, video, digital documents, or other digital media formats or a library accessible through the internet. Objects can consist of digitized content like print or photographs, as well as originally produced digital content like word processor files or social media posts. In addition to storing content, digital libraries provide means for organizing, searching, and retrieving the content contained in the collection. Digital libraries can vary immensely in size and scope, and can be maintained by individuals or organizations. The digital content may be stored locally, or accessed remotely via computer networks. These information retrieval systems are able to exchange information with each other through interoperability and sustainability.
In the context of libraries and archives, an inventory refers to a detailed list or record of the items, materials, or resources held within a collection.
In the post-Stonewall era, the role of libraries in providing information and services to LGBTQ individuals has been a topic of discussion among library professionals. Libraries can often play an important role for LGBTQ individuals looking to find information about coming out, health, and family topics, as well as leisure reading. In the past 50 years, advocate organizations for LGBTQ content in libraries have emerged, and numerous theorists have discussed various aspects of LGBTQ library service including privacy concerns, programming, collection development considerations and librarian/staff education needs, as well as special services for juvenile and teen patrons.
Collections management involves the development, storage, and preservation of cultural property, as well as objects of contemporary culture 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, 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.
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.
"Found in collection" (FIC) is a term used by a museum to refer to "undocumented objects that remain without status after all attempts to reconcile them to existing records of permanent collection and loan objects are completed". Despite the best efforts of museum staff, museums often have FIC items. This term was developed so that collections with incomplete provenance would be handled ethically and with transparency. Depending on the paperwork and information accompanying the material, the museum has several choices in how to proceed.
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.
