Dewey Services : Overview

概觀

The Dewey Decimal Classification System continues to evolve to reflect the changing world around us—from scientific discoveries and shifting geographies to emerging cultures and lifestyle trends. Easier than ever to use, Dewey works the way you do—online or by the book.

As the world changes, so do the demands of library users. They search new topics, use new languages and approach traditional knowledge resources with a new set of questions.

Keeping pace with knowledge and helping you organize it is what the Dewey Decimal Classification (DDC) system is all about. Our editorial staff and international policy committee work closely with librarians to ensure the revisions, expansions and additions we make to DDC truly reflect the needs of today’s library users. It’s input from experts like you that continues to make Dewey timely, relevant and indispensable.

Dewey also keeps pace with the way you work. While the print version remains as popular as ever, most libraries today want both a print and an online version. The print version is a ready resource for librarians who prefer using hard copy, while WebDewey offers all the advantages of online information access, plus regular updates throughout the year.

WebDewey: Web-based service with quarterly updates

WebDewey is an online version of the complete Dewey Decimal Classification system. Using a standard Web browser, you have unlimited access to an enhanced version of the DDC 22 database, including Relative Index terms and built numbers not available in the print edition.

Staying current is easy

Because WebDewey is a subscription-based service, you automatically receive quarterly updates to the DDC system. The changes include new Library of Congress Subject Heading mappings, index terms and built numbers.

Customize and share your local

Add your own online notes to reflect your local classification practices. This annotation feature also allows you to share those notes with others in your institution.

Simplify your workflow

WebDewey is more than a cataloging tool; it’s a productivity tool as well. Eliminate repetitive tasks and reduce time-consuming ones with automated features and faster keyboard navigation.

DDC 22: Revised and updated to reflect today’s world

Classify anything that’s new
