After extensive evaluation of the MyLibrary@CDL prototype and a review of CDL’s emerging priorities, active development of this system is being suspended indefinitely. The prototype will remain available for use on an experimental and “as-is” basis. At the same time, CDL intends to share the considerable body of information gained from the evaluation process, and to work with any UC campus library that wishes to develop a user-customizable portal or add customization features to its web site. A statement on this decision, and detailed reports on the MyLibrary@CDL focus groups and user observation studies, can be found at: [http://www.cdlib.org/libstaff/system_services/projects/mylibrary/]. Many thanks go to the Tools and Services Working Group, the evaluation liaisons who conducted focus group sessions, and especially to the users who helped in this evaluation effort.
