Known as the Beaver Collection, after General James Addams Beaver, this digital collection is comprised of materials from four Pennsylvania libraries, and consists mainly of "Pennsylvania county histories, atlases, and Civil War regimental histories." Visitors can search the collection by title, author, or subject. A particularly interesting piece of history from the collection can be found by clicking on "Browse All Titles", and scrolling down to image #9, which is a multi-part document that lists thousands of names of German, Swiss, Dutch, French, and other immigrants in Pennsylvania from 1727-1776. In addition to names, the multi-lingual document also provides the ships they came on and when they arrived in Philadelphia. Visitors interested in saving any of the documents in the collection can save them in their "Favorites", and they can choose to save a whole document or just a page within the document.
