Dewey Decimal Classification Ownership by OCLC

The question asks about the year when the Dewey Decimal Classification (DDC) system came under the ownership of OCLC (Online Computer Library Center).

Understanding Dewey Decimal Classification (DDC)

The Dewey Decimal Classification (DDC) is a widely used system for organizing library materials. It was first introduced by Melvil Dewey in 1876. The DDC organizes all knowledge into ten main classes, represented by numbers from 000 to 900. These classes are further divided into more specific categories using decimal points, allowing for a detailed and systematic arrangement of books and other resources in libraries worldwide. The primary goal of the Dewey Decimal Classification is to provide a structured way for libraries to classify, shelve, and retrieve materials efficiently, making it easier for users to find the information they need.

Understanding OCLC (Online Computer Library Center)

OCLC, or the Online Computer Library Center, is a global library cooperative that provides shared technology services, original research, and community programs for its member libraries. Founded in 1967, OCLC's mission is to further access to the world's information and reduce information costs. It is well-known for operating WorldCat, the world's largest online catalog of library materials. OCLC plays a crucial role in supporting library operations, resource sharing, and bibliographic control across the globe.

Dewey Decimal Classification Acquisition by OCLC

The ownership of the Dewey Decimal Classification (DDC) system transitioned to OCLC in a specific year. This acquisition was a significant event in the history of library science, as it brought one of the most prominent classification systems under the stewardship of a major global library cooperative. OCLC has since been responsible for maintaining, updating, and publishing the Dewey Decimal Classification, ensuring its continued relevance and usability for libraries around the world.

• Prior to OCLC's ownership, the Dewey Decimal Classification was managed by the Forest Press, which had been responsible for publishing and updating the DDC for many years.
• In 1988, OCLC acquired Forest Press, and with it, the rights and responsibilities for the Dewey Decimal Classification system.
• Since 1988, OCLC has continued to develop and disseminate the DDC, adapting it to modern information needs and technological advancements.

Therefore, OCLC has owned the Dewey Decimal Classification since 1988.
