Sept. 95 - Sept. 97

The Human-Computer Interaction Laboratory (HCIL) at the University of Maryland is assisting the Library of Congress (LC) in designing user interfaces and organizing the content of the National Digital Library (NDL). The early decisions made will influence how the NLD evolves as well as how other organizations develop digital libraries. LC leadership in digital libraries will depend on how users are able to access and use digital information as the collection grows larger and virtual collections cross the boundaries of individual digitized collections.

The goal of this collaboration is to establish a user-centered design team for the NDLP, to create interface prototypes that serve a wide range of users, and to develop a variety of tools and widgets that LC may incorporate into future implementations.

Beginning in the fall of 1995, HCIL team members met regularly with an LC team composed of librarians, managers, and technical staff to identify key interface challenges and brainstorm design approaches and features. As part of these efforts an extensive user needs assessment was conducted to determine characteristics of LC users and the types of information needs they bring to the Library. The needs assessment report presents a user typology with nine type/task components and identifies a series of interface challenges broken into content and user strategies categories. A prototype interface is now evolving over over several iterations. The prototype is not meant as a design that will itself be fully implemented but rather a means to explore different design problems and suggest design techniques and widgets to the LC implementation team.
