|View of the Yosemite Valley, 1865, by Thomas Hill - Collection of The New York Historical Society|
American Libraries magazine has a great article on America's NPS libraries throughout the country. I wonder how many people even know about this wonderful resource? These libraries hold a great many resources on the history, geology, geography, and preservation of, as Ken Burns put it, "America's best idea." The Parks' collection is searchable online, so one can limit results to a particular park, such as the Grand Canyon or Yosemite, as examples. The Parks libraries also participate in the world-wide Ask-a-Librarian program where you can chat with NPS librarians to find out more about our national parks. What a truly great, underutilized and largely unknown library resource!
