These two books were conceived and designed for audiences with varied interests, time commitments, and information needs — from the tourist to the scholar. Philadelphia Architecture (the second, updated version of the original 1984 edition) tracks the city’s cultural, historical, and artistic development. A clear cross-referencing system moves the reader between a chronologically (rather than geographically) organized catalogue of 200 buildings and styles, with a section of walking and driving tours and maps linked to public transit. Best Buildings presents similar information geographically, with less detail, serving as an alternative architectural guide for readers whose time is limited or whose principal focus is the city’s most notable historic structures.
