Includes the catalog of the records for buildings and building groups scattered across PA. It surveys PA¿s 300 years of architecture, describes geographical and cultural influences on development patterns within the Commonwealth¿s major geo-cultural regions, and catalogs the Historic American Buildings Survey (HABS) holdings for each of those regions up to 1990. There is no great body of publications to consult for a statewide survey such as this. Also, because the limited literature is skewed toward early high-style buildings in the Phila. region and because HABS surveys in PA have not been comprehensive, this book should be viewed as a ground-breaking work on PA¿s architectural heritage. Over 100 illustrations.
