Abstract

The Computing and Information Technology Interactive Digital Educational Library (CITIDEL) was developed as part of the collection-building effort of the National Science Digital Library (www.nsdl.org). Essentially, it supports a collection of metadata about resources stored at other sites, such ACM, DBLP, NDLTD, etc., in addition to having a small collection in its own right. As of January 1, 2004, it has 12 source collections, and contains metadata on over 440,000 resources. During the year 2003, it received an average of over 33,000 hits per month, by users from at least 22 countries. With suitable enhancements, we believe CITIDEL can support a much wider base of users, and have significant impact on the teaching and learning of those interested in computing and information technology.
