"Most of the county tax lists covering the 1780 period are published in the Pennsylvania Archives, except for Northampton and Westmoreland counties. Because the 1780 tax lists for these two counties for the most part are available elsewhere, and becasue the tax lists int he Pennsylvania Archives are not compiled in the conveneient statewide format, as has been done with many of the federal census records, the compilers [of this book] felt the definity need to arrange these records in a statewide finding list entitled Pennsylvania In 1780. Pennsylvania In 1780 contains all the names listed in the circa 1780 tax lists in alphabetical order showing the county and township in which the anme was shown. As the tax lists often contained additional information on each name it would be well when finding an individual in Pennsylvania In 1780 to check the original source." [from the preface]
