In a university environment, the library can benefit from interest in the digital future on the part of other concerned groups. Computer science departments are natural partners in the development of digital libraries. Professional societies, for-profit companies, and foundations are also potential sources of support. Cornell University Library (New York) has worked closely with a variety of interested individuals and organizations in providing access to and preservation of digital materials. This paper describes the evolution of some of those projects and the resulting innovations and technology enhancements. Projects covered include: The Mathematics Book Collection; TEEAL (The Essential Electronic Agricultural Library); ICE (Internet Connections for Engineering); Project Nomad, a research project in which students in two experimental courses are each issued a laptop computer with a wireless modem; Project TULIP, a cooperative research project to test networked delivery and use of electronic journals; a grant titled Security and Reliability in Component-Based Digital Libraries; NEEDS (National Engineering Education Delivery System); and Project Euclid, a pilot project developed to help independent mathematics and statistics journals by setting up an infrastructure that will empower them to publish on the World Wide Web.
