I have an algebra book that I'm trying to get put into electronic form
so that I can CC-license it. Euclid's Elements are available from the
Perseus project and other Web sites.

There is a wide assortment of materials and Web sites loosely
catalogued at http://librarianchick.pbwiki.com/#Mathematics/Calculators.
It could use the attentions of a team of librarians to create and
maintain a detailed catalog. Stacy Reed the Librarianchick would be
glad of our assistance. Some of the links have disappeared, so it
would also be useful to create a permanent archive somewhere. Some of
them can doubtless be retrieved using the Wayback Machine at the
Internet Archive. http://www.archive.org/web/web.php
