Buffalo Architecture and History
Chuck LaChiusa's wonderful guide to the architecture and history of Buffalo, NY, also happens to host an impressive illustrated furniture glossary. It's one of the best resources we've seen on the web for understanding different movements, periods, and styles (Federal, Adamesque, Renaissance Revival), and other miscellaneous American furniture lingo from finials to fluting. The architecture section is also fascinating, containing a huge database of buildings browsable by name, address, and architect.
