Architecture aficionados will delight in the Pacific Coast Architecture Database (PCAD). Alan Michelson, head of the Built Environments Library at the University of Washington-Seattle, first launched the site in 2002 as "CAD" (California Architecture Database). In 2005, a career move to the University of Washington allowed him to expand the project to include Oregon and Washington. PCAD documents information on impressive architecture and architects, including history, geography, and "impact[s] on the built environment." The query bar at the top of the site welcomes users to "search for a person, firm, or building." There are also pages dedicated to each of these three categories. On the People page, users will find a list of more than 8,000 architects, designers, and similar figures. The Buildings page highlights more than 20,000 structures (listed by address). Clicking on an address reveals additional information such as maps, images, and historical details. Finally, the Firms page provides an alphabetized index of more than 6,000 architecture and design firms. Additionally, the More tab provides articles, exhibitions, pictures, and access to the PCAD Blog (last updated in 2015).
