The National Genealogical Society (NGS) always has informative articles on its blog, UpFront with NGS. By subscribing to the NGS blog email service, I learned about the Federal Library Directory, an interactive map from the Library of Congress. A portion of the news release is below.
Read more of the press release which includes a link to important information about using the interactive maps. There is a caveat: The mapping software is only viewed using the Mozilla Firefox browser and the link provided loads slowly. If you are unable to use Firefox, a pdf file of the directory is available.
