Dewey-free classification

Last updated

Dewey-free (also Dewey free, Dewey-less, or word-based) refers to library classification schemes developed as alternatives to Dewey Decimal Classification (DDC). Dewey-free systems are often based on the BISAC subject headings developed by the Book Industry Study Group, and are typically implemented in libraries with smaller collections. Instead of using numerical notation to indicate a document's shelving location, Dewey-free systems organize documents alphabetically by natural language words. Dewey-free systems have been implemented in both public and school libraries.

Motivations

A primary motivation for the development of Dewey-free systems is to eliminate DDC's numerical notation, which many library patrons find intimidating. Abandoning numerical notation in favor of natural language words may also facilitate browsing. [1]

Adoption of classification is often seen as part of a greater trend of using a "bookstore model" to deliver library services. This trend gained traction in 1998 with an article by Los Angeles librarian Steve Coffman. [2] While some librarians see this as a beneficial approach that will make patrons more comfortable and increase circulation statistics, others disagree with the approach, particularly as large bookstores such as Borders Group have met severe financial challenges.

Many Dewey-free proponents believe that Dewey is outdated and ill-suited for non-academic environments. [1] [3] DDC organizes documents not only by subject, but also by academic discipline. [4] This leads to materials on the same topic being filed in wildly disparate locations. For example, Dewey places books about railroad trains in both the 380s and the 620s. [5] The discipline-based orientation is also problematic for categorizing interdisciplinary works [6] and non-academic titles, which make up the bulk of most public libraries' non-fiction holdings.

DDC has also faced a number of critiques for its biases. Scholars and catalogers have specifically criticized its marginalization of developing countries and continents, [7] [8] [9] [10] [11] [12] Christian-centrism, [7] racism, [13] [14] sexism, [15] homophobia, [16] and marginalization of intersex people. [17] Some proponents of Dewey-free systems suggest that abandoning DDC in favor of new schemes may address these problems, but the literature doesn't include any analysis of BISAC Subject Headings for these issues, nor have any Dewey-free libraries documented strategies for addressing these issues within the taxonomies they have devised.

Librarians who work with children point to additional benefits within their collections. They note that school library workers often have little support and few resources for teaching the DDC system to children. The numbers themselves are often opaque to younger students, who typically don't learn about decimals until late in elementary school. [3]

Adoption

In the 1970s and 1980s, public libraries in the United Kingdom and United States designed new "reader-interest classification" systems as alternatives to DDC. These systems organized materials in ways that are intuitive to non-academic users and employed modern terminology, resulting in collections that are more browsable. However, a lack of standardization led libraries to abandon these systems. Dewey-free classification schemes can be seen as new cases of reader-interest classification schemes. [18]

In 2007, the Maricopa County Library District announced that its Gilbert Library would abandon DDC in favor of a BISAC-based system. [19] The library district reported the change as a success, with non-fiction circulation improving sixfold. [20]

In 2009, the Rangeview Library District became the first library district to fully convert to a BISAC-based scheme. Rangeview's classification system, which is branded as "WordThink", is based on BISAC headings. [21]

In 2011, the librarians at the Ethical Culture School in New York City developed a Dewey-Free system called Metis. The school's novel approach incorporated focus groups of students from Kindergarten through the Fifth Grade in designing the system. [5]

The Darien Library in Connecticut employs a hybrid approach to classification. While books are still organized by DDC number, DDC categories are "clumped into eight broad categories," known as glades. [1] A glade groups together books from several Dewey classes that Darien librarians feel may be useful to similar groups. For example, the Places glade is intended for international travellers, and combines books from the 400s (Languages) and 910s (Travel and Geography). [22]

The Nyack Library used a "marketplace" system similar to Darien's glades. [23] However, after complaints from community members, the library reverted to a traditional DDC collection in 2013.

The King County Library System announced in 2014 that all 48 of its branches will convert their fiction picture book collections to a Dewey-free subject classification system. [24]

Evaluation

There has been very little formal evaluation of Dewey-free systems, even by libraries that have implemented them. [21]

Many libraries point to an increase in circulation statistics—either for a particular topic or for the non-fiction collection as a whole—as a measure of the success of their Dewey-free systems. [3] [5] However, the correlation between circulation statistics and library classification scheme is not easy to demonstrate. [25] [26] Dewey-free reclassification projects are often undertaken in conjunction with other projects that aim to better merchandise a library's holdings, so it can be very unclear how much of a circulation increase can be attributed to a new classification scheme. [27] Furthermore, library scholars typically warn against using circulation statistics as the sole metric of any project's success, because such statistics fail to account for materials used within the library, materials that were circulated but never read, or materials that were circulated but failed to provide users with the information they needed. [28]

Call numbers are generally not indexed by Integrated Library Systems, so the adoption of word-based classification systems has had little impact on information retrieval quality within library catalogs to date. [29]

Criticisms

Critics of the new systems argue that BISAC's broad categories actually impede browsing, as many different subtopics are interspersed with one another. They prefer DDC's arrangement of materials by specific subject. They also argue that many of the issues addressed by Dewey-free systems could be resolved much more easily with improved signage and book labels. [30]

Even proponents of Dewey-free systems note that BISAC-based classification systems would be unsuitable for libraries with large or specialized collections. [31] Critics have also questioned the pedagogical value of Dewey-free classifications, questioning whether library patrons used to a Dewey-free system will have the skills necessary to navigate collections classified according to DDC or Library of Congress Classification. [5]

Critics have also noted that using English words instead of numbers for all classification sends a message that libraries are only interested in serving English speakers. [1]

Dewey Decimal Classification Library classification system

The Dewey Decimal Classification (DDC), colloquially the Dewey Decimal System, is a proprietary library classification system which allows new books to be added to a library in their appropriate location based on subject. It was first published in the United States by Melvil Dewey in 1876. Originally described in a forty-four-page pamphlet, it has been expanded to multiple volumes and revised through 23 major editions, the latest printed in 2011. It is also available in an abridged version suitable for smaller libraries. OCLC, a non-profit cooperative that serves libraries, currently maintains the system and licenses online access to WebDewey, a continuously updated version for catalogers.

Library classification Systems of coding and organizing documents or library materials

A library classification is a system of knowledge organization by which library resources are arranged and ordered systematically. Library classifications a notational system that represents the order of topics in the classification and allows items to be stored in that order. Library classification systems group related materials together, typically arranged as a hierarchical tree structure. A different kind of classification system, called a faceted classification system, is also widely used, which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in many ways.

Melvil Dewey Inventor of the Dewey Decimal system

Melville Louis Kossuth "Melvil" Dewey was an influential American librarian and educator, inventor of the Dewey Decimal system of library classification, a founder of the Lake Placid Club, and a chief librarian at Columbia University. He was also a founding member of the American Library Association but resigned in 1905, due to allegations of sexual harassment, racism, and antisemitism.

S. R. Ranganathan Indian mathematician and librarian

Shiyali Ramamrita Ranganathan (S.R.R.) was a librarian and mathematician from India. His most notable contributions to the field were his five laws of library science and the development of the first major faceted classification system, the colon classification. He is considered to be the father of library science, documentation, and information science in India and is widely known throughout the rest of the world for his fundamental thinking in the field. His birthday is observed every year as the National Librarian Day in India.

A faceted classification is a classification scheme used in organizing knowledge into a systematic order. A faceted classification uses semantic categories, either general or subject-specific, that are combined to create the full classification entry. Many library classification systems use a combination of a fixed, enumerative taxonomy of concepts with subordinate facets that further refine the topic.

OCLC Global library cooperative

OCLC, Inc., doing business as OCLC, is an American nonprofit cooperative organization "dedicated to the public purposes of furthering access to the world's information and reducing information costs". It was founded in 1967 as the Ohio College Library Center, then became the Online Computer Library Center as it expanded. In 2017, the name was formally changed to OCLC, Inc. OCLC and its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog (OPAC) in the world. OCLC is funded mainly by the fees that libraries pay for the many different services it offers. OCLC also maintains the Dewey Decimal Classification system.

Henry Evelyn Bliss was the author of a classification system he called Bibliographic Classification which is often abbreviated to BC and is sometimes called Bliss Classification. He was named one of the 100 most important leaders in the field of library and Information science in the 20th century by American Libraries in December 1999, which praised his “subject approach to information” as “one of the most flexible ever conceived.” Despite these praises, Bliss was “met with apathy and even derision in his efforts” during his lifetime. His classification system was generally disregarded in favor of other more established classification systems such as the Dewey Decimal System created by Melvil Dewey and the Library of Congress Classification system, causing “more than one author” to label him as a, “prophet without honor.” Although Bliss was an American, his system was more popular in British libraries than in American libraries. A second edition of the system has been developed in the United Kingdom in 1977. Several volumes have been published.

The Korean Decimal Classification (KDC) is a system of library classification used in South Korea. The structure and main level classes of the KDC are based on the Dewey Decimal Classification. The KDC is maintained and published by the Classification Committee of the Korean Library Association. The first edition of the classification was published in 1964; the most recent edition is the sixth edition published in 2013. Almost all school and public libraries in South Korea use the KDC to organize their collections, as well as the National Library of Korea and some university libraries.

Metis is a Dewey-free library classification system developed and implemented in 2011 by Sue Giffard, Tali Balas Kaplan, Jennifer Still, and Andrea Dolloff, the librarians at the Ethical Culture School in New York City. The system places the thinking, interests, information needs and information-seeking behavior of children at its center. It was developed as an alternative to the Dewey Decimal Classification System and the practices which customarily accompany that system in school and public libraries in the United States: namely, the alphabetical arrangement of fiction by author, and the frequent arrangement of biographies in alphabetical order by biographee. The Metis system was designed to encourage productive independent browsing by children, as well as allowing for successful catalog searching by elementary school students.

The British National Bibliography (BNB) was established at the British Museum in 1949 to publish a list of the books, journals and serials that are published in the United Kingdom and Republic of Ireland. It also includes information on forthcoming titles. This is the single most comprehensive listing of UK titles. UK and Irish publishers are obliged by legal deposit to send a copy of all new publications, including serial titles, to the BNB for listing. The BNB publishes the list weekly in electronic form: the last printed weekly list appeared in December 2011.
