Under what title the DDC first time published?

The first edition of the Dewey Decimal Classification (DDC) system was published in 1876 under the title “A Classification and Subject Index for Cataloguing and Arranging the Books and Pamphlets of a Library.” This original edition of the DDC was relatively small, with just 10 main classes and a few hundred subcategories.

Since its initial publication, the DDC system has undergone numerous revisions and updates, and it has grown to become a comprehensive classification system that covers a wide range of subjects and topics. Today, the DDC is published by the Online Computer Library Center (OCLC), and it is used by libraries around the world to organize and classify books and other materials according to subject matter.
