- Abstract
- In respect to the nature and quantity of available information, 1876 was a very different world from the one we know in the 1990s. Yet in spite of over a century of changes, the Dewey Decimal Classification (DDC), the system that helped organize a small college library, has grown to one that is helping the whole world organize its vast store of information resources. In this closing session, I would like to summarize some of the major factors that have contributed so far to the Dewey system's success as an information organization tool. I will also discuss ongoing efforts to ensure its viability in the future
