- Maps at the Library of Congress may
be downloaded and freely used, although I’d recommend always listing
them as the source and indicating any revisions made to their images if used in any kind of publication.
It is also possible to order copies of maps they have not yet scanned,
for a charge based on the size of the document/map (that's how the Rhea map below came to be on their web site). They are
usually fairly prompt to answer questions posted through the “Ask a
Librarian” link on their site.

- Maps at the Tennessee State Library and Archives may be downloaded
and used, but you may need to complete a form indicating what you plan
to use them for. And they require you to always list them as the
source and any revisions made to their images if used in any kind of publication. It is also
possible to order copies of maps they have not yet scanned, for a
relatively small charge, but you will have to complete the form.

- Maps at the David Rumsey Collection may be downloaded, but the images
are copyrighted, and thus use is restricted. If you wish to
download images at their highest resolution you will need to register
then log in each time you access the site thereafter. It doesn't
anything to register. They might give permission for some uses; just be
sure and ask first.

- The use of the term “et al.” below means that at least one revision
was published, usually over a span of several
years. And the date given may not be for the first version. For
example, Rand McNally published their first atlas in the 1870s and
continues to publish maps and atlases to this day.
- Prior to the late 1800s, most, if not all, color maps were colored by
hand with watercolor. Some of the larger companies literally had rooms
filled with women and men doing this day in and day out.
