SSRN Author Pages
A useful feature of the Social Science Research Network (SSRN) and Economics Research Network (ERN) is the "Author Home Pages." These can be reached from their search page by searching in the author field, and then clicking on the desired author. You will then find contact information, affiliations, and a list of papers and abstracts in SSRN. Some people put this page in their e-mail signature; the format is http://papers.ssrn.com/author=XXX where XXX is the author ID (the last part of the URL from their search page).
