250+ Killer Digital Libraries and Archives
Hundreds of libraries and archives exist online, from university-supported sites to individual efforts. Each one has something to offer to researchers, students, and teachers. This list contains over 250 libraries and archives that focus mainly on localized, regional, and U.S. history, but it also includes larger collections, eText and eBook repositories, and a short list of directories to help you continue your research efforts.
The sites listed here are mainly open access, which means that the digital formats are viewable and usable by the general public.
Efforts were made to go to the root source for these collections. In other
words, if you're seeking the American Memory Project, which was created and
housed at the Library of Congress, then you'll find the link for the Library
of Congress rather than the link for American Memory (although we included
that link in the description of the Library of Congress listing). The root
sources, in most cases, will lead you to collections that are too numerous to
list here. In fact, it would be impossible to list all sources and we know we
may have missed some favorites.
