Frequently asked questions regarding DDC print editions

Why are you no longer publishing new print editions?

On a seven-year publication cycle, print editions fall out of date very quickly, and we can more effectively keep you updated with the latest changes to the Dewey Decimal Classification through WebDewey.

After June 2018, is WebDewey the only way to get the most up to date changes to DDC?

Yes.

Who should I contact if I would like to purchase any Dewey print edition or WebDewey?

To purchase any Dewey product, please complete the appropriate printable order form.


The Dewey Decimal Classification (DDC) system is the world’s most widely used way to organize library collections. The DDC constantly updates to enable better discovery across any topic in multiple languages. Because the DDC is easy to use, you can increase the visibility of your materials quickly and efficiently.
