The Sanborn maps belong to the Library of Congress which has turned them
over to ProQuest to be digitized. Obviously someone from LOC and/or
Proquest can give more detail.

"Today, fire insurance maps are used for a wide variety of research
purposes including genealogy, urban history and geography, historical
preservation, and environmental studies. The Library accumulated its
unsurpassed collection of fire insurance maps primarily through
copyright deposit. In addition, the Bureau of the Census transferred a
set of maps updated with pasted-on corrections through to the mid-1950s
to the Library of Congress in 1967."

*Scope of the Collection*

*Digital Sanborn Maps* was created from ProQuest Information and
Learning's microfilm collection of 660,000 Sanborn Maps, which were
filmed from the Library of Congress' collection. The Library's Sanborn
collection includes all maps submitted to the Library through copyright
deposit and a set of maps transferred to the Library from the Bureau of
the Census. Maps from the Bureau of the Census include corrections
issued by the Sanborn Company that were pasted over the original map
sheet. Maps acquired through copyright deposit remain in their original
form.
