When was DDC developed and who devised it?

The Dewey Decimal Classification (DDC) system was developed by Melvil Dewey in the late 19th century. Dewey was an American librarian and library innovator, and he is best known for his contributions to library science, including the development of the DDC system.

According to the Online Computer Library Center (OCLC), the DDC system was first published in 1876. It was initially developed as a way to organize and classify the books in the Amherst College Library, where Dewey was working at the time. The DDC system was later revised and expanded, and it has become one of the most widely used library classification systems in the world.

Dewey is considered to be one of the pioneers of modern library science, and his contributions to the field have had a lasting impact on the way that libraries are organized and managed. In addition to the DDC system, he is also known for his work on library management and administration, as well as his advocacy for universal access to knowledge.
