Minimize volunteer and staff training timeStaffer reshelving books

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.

Library user browsing shelvesHelp 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.
