----------------------------Original message---------------------------- We have a patron in our library today who is preparing an article for publication on piloting charts published by the U.S. Hydrographic Office between 1920 and 1940. Any assistance would be appreciated. We've already exhausted our own resources, the Library of Congress's Geography and Map Division database (telnet locis.loc.gov), and the University of California's MELVYL subsystem on telnet database.carl.org. Thanks. Gregory Shelton U.S. Naval Observatory Library Washington, D.C. [log in to unmask] (P.S. I have his address, and he will be back to visit us if you cannot respond today or next week, etc.)
