Presented by the University of California Berkeley's (UCB) Earth Sciences and Map Library, the Browse Our Digital Map Collection Web site lets visitors do just that. Several thousand scanned maps from the collection are available and can be searched via the UCB Library Pathfinder program. After orientating oneself to the peculiarities of the search program, which seems more daunting than it actually is, the vast collection can be accessed quite easily. The extensive aerial photographs, historical maps, and other similar offerings make the search worth the effort.
