Ken,
I reply to your question to the listserv about historic topo maps:
The book _Map Index to Topographic Quadrangles of the United States,
1882-1940_ by Riley Moore Moffat, c. 1985, indexes the 1:125,000 and
1:250,000 maps by state. On page viii of the forward it is
explained that the 1:250,000 was used for undeveloped areas of the west.
There are many 1:125,000 sheets in the west also. Unfortunately, this
great book excluded the early 6-minute (Los Angeles County), pre-1940
7.5-minute quads and the 1:31,380 series of the 1940's.
I'm currently making an inventory of my library's historic topographic
maps. If you would like to compare notes please feel free to reply to:

I'm very interested in finding any index maps for the 6-minute series or
the 1:31,380 scale series.
