"This publication lists 1,725 grants of $5,000 or more awarded by 474 foundations, from 2003 through 2007. It covers grants to public, academic, research, school, and special libraries, and to archives and museums for activities related to conservation and preservation." Using this resource, you can find out who is giving grant money, where, and for what purpose.
I found this link in the monthly Heritage News e-newsletter from the National Park Service, which can be read online, or emailed to you.
