Since it's emergence in 1993, the World Wide Web has been an information free-for-all where anyone can post anything. Search engines can be useful, but are usually indiscriminate. A January 1997 search for "seismic AND design" on the Alta Vista search engine yielded "about 10000 matching the query, in no particular order". While the web remains cluttered with trivia, there is an increasing number of high-quality resources provided by distinguished and credible institutions and organizations. The list of resources on this page is far from comprehensive, but includes sites that I have found worthwhile. One of the keys to finding good information on the web is starting in the right place, since good sites tend to include good links. Most of the sites listed here are good entry points to the growing wealth of information that is coming on line.
Many educational and professional organizations and commercial companies use the web to distribute information, often including web-based version of reconnaissance reports and other information. There are also many research labs, particularly in the area of earth science and seismology. The listing here is quite limited, but many of these sites maintain lists of links to other resources, serving as a useful starting point for locating high-quality information.
The web also provides access to library search tools for literature related to earthquake engineering. The following are some particularly useful sources.
