The Cornell University Library (CUL) system comprises 20 member libraries representing one of the 10 largest research libraries in North America. With over 7 million printed volumes in its collections, nearly 65,000 journal and magazine subscriptions, more than 100,000 sound recordings, and nearly a quarter of a million maps, CUL provides an intellectual backbone to the university’s activities. It has been also a pioneer in the digitalization of historical material to be included in online archives. The digital archives include comprehensive collections of images, texts, data or videos that can be browsed and/or searched for free. Some examples are: the Political Communications Web, a project which entails a planning effort to develop effective methodologies for the systematic, sustainable preservation of Web-based political communications, and Making of America, a multi-institutional initiative to create and make accessible over the internet a distributed digital library of important material about US history. An additional resource is the DSpace digital repository, an open source system that captures, stores, indexes, preserves, and redistributes digital research material, where users can access full-text material for free including working papers and research. The CUL site features an intuitive outline thus making its navigation straightforward and enjoyable.
