For much of the historic data the authors acknowledge their indebtedness to the authors of previous Philadelphia books, notably "Philadelphia, the City and Its People" and "The Literary History of Philadelphia", Ellis Paxon Oberholtzer; "Old Roads Out of Philadelphia" and "The Romance of Old Philadelphia", John Thomson Faris; "The History of Philadelphia" and "Historic Mansions of Philadelphia", T. Westcott; "The Colonial Homes of Philadelphia and Its Neighborhood", Harold Donaldson Eberlein and Horace Mather Lippincott; "Colonial Mansions ", Thomas Allen Glenn; "The Guide Book to Historic Germantown", Charles Francis Jenkens; "Germantown Road and Its Associations", Townsend Ward. Ph. B. Wallace, of Philadelphia, photographed some of the best subjects. The original boundaries of Philadelphia remained unchanged for one hundred and seventy-five years after the founding of the city, the adjoining territory, as it became populated, being erected into corporated districts in the following order: Southwark, 1762; Northern Liberties, 1771; Moyamensing, 1812; Spring Garden, 1813; Kensington, 1820; Penn, 1844; Richmond, 1847; West Philadelphia, 1851; and Belmont, 1853. In 1854 all these districts, together with the boroughs of Germantown, Frankford, Manayunk, White Hall, Bridesburg and Aramingo, and the townships of Passyunk, Blockley, Kingsessing, Roxborough, Germantown, Bristol, Oxford, Lower Dublin, Moreland, Byberry, Delaware and Penn were abolished by an act of the State legislature, and the boundaries of the city of Philadelphia were extended to the Philadelphia county lines. Such of these outlying communities as had been settled prior to the Revolution were closely related to Philadelphia by common interests, a common provincial government and a common architecture. For these reasons, therefore, it seems more logical that this treatise devoted to the Colonial architecture of the first capitol of the United States should embrace the greater city of the present day rather than confine itself to the city proper of Colonial times. Otherwise it would be a problem where to draw the line, and much of value would be omitted. The wealth of material thus comprehended is so great, however, that it is impossible in a single book of ordinary size to include more than a fractional part of it. An attempt has therefore been made to present an adequate number of representative types chosen with careful regard, first, to their architectural merit, and second, to their historic interest. Exigencies of space are thus the only reason for the omission of numerous excellent houses without historic association and others rich in history but deficient in architecture.
