David,
The USGS came out with a book in the Eighties, I believe, "The Mapping of
America" (or something like that) which covered much of this history.
You're right -- the completion of the final 7 1/2' quad. ( sometime in the
Eighties, I think) went off with almost no fanfare!

Subject: [MapHist] History of 1:24,000 scale quadrangle maps of U.S.

Often the most recent developments in the history of cartography seem to be the
most poorly documented. This seems to be the case with the standard 7.5 minute
1:24,000 scale topographic maps of the United States. I am trying to track
down a reasonably detailed account of how they were produced during the period
between about 1945-1965, but so far have been able to gather only bits and
pieces of information. From what I have been able to gather, most of these
maps were based on aerial photographs taken during the 1930s. They seem to
have first been produced in quantity by the Army Map Service (AMS) during the
war. Most or many of the maps issued by the U.S.G.S. between 1945 -1960 seem
to have been based on work done by the AMS. Because of budget constraints,
apparently almost nothing has been done to update the contour lines on these
maps since their initial appearance, although planimetric data has been added
to so me of them
Does anyone know of sources that can confirm, correct, or fill out this
sketch? I have checked Thompson'sMaps for America, and tried to track down
additional information via the Web. Thanks.
