----------------------------Original message---------------------------- Not everything at USGS is as "gloom and doom" as some may think. There is indeed a 'Reference Collection and Historical Map Archives. According to a description I have it "... includes maps from the 1880's to date and is divided into three chronological segments: 1880's-1933; 1934-1984; and 1985 to date." Furthermore, "... the early years of the map archives may not be comp lete. In more recent years, however, the archives contain at least one copy of each NMD topographic map published or reprinted." The contact person is Ms. Mary E. Graziani (703) 648-4556. Address is NMD Historical Map Archives, USGS National Center, Room 2B123, Mail Stop 522, Reston, VA 22092. They also have computer-based indexes of the 1880's-1933 and the 1985 to date segments. David A. Cobb Harvard Map Collection
