A telephone survey and interviews were used to compile this directory of map resources in San Francisco, California. The directory listings are divided into collections and sources of maps. Within the two sections, the entries are subdivided by type of institution. Collection locales include academic and government libraries, corporations, and association. Sources include government agencies, associations, bookstores, and dealers. Each citation provides an address and telephone number and comments on special features of that collection or source such as subject coverage and availability of free materials. In a preface, some conclusions are drawn from the initial survey as to the state of map resources in San Francisco. (SL)
