WebDewey: the right tool to organize your collection
WebDewey is the electronic version of the Dewey Decimal Classification® (DDC) system. It is a full representation of all published numbers, plus other mappings and new terms that have been approved by the Dewey Editorial Policy Committee (EPC). It puts the power of the world’s most widely used library classification system in the hands of metadata managers to efficiently organize their collection(s).
WebDewey is the easiest way to use the DDC to organize and classify library collections. With WebDewey, metadata managers have the most up-to-date DDC numbers available that are based on an array of continually evolving topics and languages. WebDewey also includes:
- searching or browsing DDC numbers, Library of Congress Subject Headings (LCSH) and mapped MeSH headings
- adding your own notes and displaying them in context
- an easy-to-navigate, simple user interface that is suitable for the novice as well as the power user
Dewey Print-on-Demand
If you prefer to have offline access to DDC, we have you covered there, too. We now offer a Dewey Print-on-Demand option. This 4-volume set includes the latest changes and topics available in the DDC and will be updated on an annual basis.
