Organize your materials with the world's most widely used library classification system.
Organize your collection
Libraries big and small the world over use the Dewey Decimal Classification® (DDC) system to help make sense of today's complex library collections.
Get timely updates
Get updates to the DDC through continual updates to the WebDewey service. The Dewey editorial team continually identifies new trends in published topics to include in the DDC to make it work better for you and your library. Email email@example.com with your Dewey questions and concerns.
Minimize volunteer and staff training time
Many libraries rely on volunteers and temporary staff to manage day-to-day tasks such as re-shelving books. The DDC's simple, number-based format makes it easy for these helpers to know exactly where a book should fit on the shelf. They can re-shelve books quickly and have confidence they're doing it correctly.
Help patrons feel more comfortable in the library
Non-regular library users can be intimidated by the rows and rows of shelves, searching the catalog, and even asking a librarian for help. With its subject-based classification system, the DDC encourages patrons to independently browse the catalog, the stacks, and even your programming schedule to find what they need. Once they find the topic area they want, patrons can comfortably browse the items to get a better understanding of your collection.
