A library for the fifteenth through the twenty-first centuries.

The University of California, San Francisco (UCSF), began developing a program for a new library in 1977, started the design in 1985, began construction in 1988, and opened the library in September 1990. The primary objectives were to design and build a facility that would house print collections under optimal conditions, allow for ten years' growth, be flexible enough to permit future reconfiguration, support present and future technologies, and provide beautiful spaces in which to study. The planning process is summarized, planning concepts are outlined, and considerations for the electronic library are briefly reviewed.
