Important update on DDC 23 print products: In an effort to provide libraries with the most up-to-date information available, OCLC has decided to discontinue publishing English-language print edtions of the DDC. All remaining English-language print copies of DDC 23 have been sold. Remaining English-language print copies of DDC Abridged 15 are still available to purchase and will be sold until June 2018 or until current copies are depleted.

WebDewey provides online, web-based access to an enhanced version of the DDC based on DDC 23 and Abridged Edition 15.

  • Order WebDewey through the Nebraska Library Commission at the group rate. Pricing information is on the order form.
