Architecture and Building "Topics covered by this guide include architecture, building and construction, design, housing, planning, preservation, facility management, energy and the environment, and landscape architecture. Types of listings range from discussion groups to electronic publications to databases -- and of course a wide variety of web sites. This is a selective guide. Links to more comprehensive link collections are included. For some topics just one or two sites with good links to the net resources in that topic are listed.
