Architect's Portable Handbook by Pat Guthrie initiated the Portable Handbook series and has been very successful. It is essentially a technical guide - organized by CSI MasterFormat, it covers key code and standard information for building elements such as roofs and walls and key materials such as wood, concrete, and steel. Architect's Portable Design Handbook, by contrast, puts this essential information into context. It shows the architect how to work with clients, compile information, evaluate the site, explore design alternatives, evaluate user needs, work with CAD and other programs, integrate other engineering disciplines such as HVAC into a design, and make presentations. Together, these two invaluable guides are all that the architect needs to do architecture.
