Audiobook: Guide Book of Art, Architecture, and Historic Interests in Pennsylvania

This book was curated by the State Federation of Pennsylvania Women for tourists' use on a journey to Pennsylvania. Each of Pennsylvania's 67 counties has its own chapter, discussing beautiful art and buildings that may be found there (or, in lieu of art, pioneer history). These chapters were each written by a knowledgeable person from that county. While details are often sparse, the guide is an excellent starting point for individuals who wish to learn more about local history of Pennsylvania. Note: While the book was compiled in 1917, the first world war prevented its publication until 1924.

Philadelphia's Historic Firsts includes a list of all of the interesting inventions and processes created, performed, or discovered for the first time in Philadelphia. The "Commonwealth" sections are an exhaustive history of Philadelphia County and its beautiful buildings, artworks, and historical figures. Following that section, each county has a chapter, in the order in which the counties were founded. (Summary by Tatiana Chichilla)
