Bill Goffe on tch-econ let us know about a Economics Search Engine at http://ese.rfe.org/. This search seems to obey all the Google rules. I was able to restrict using a site: search, that is, typing in the box site:*.edu search terms and it did restrict to only edu sites. Cool search, but it is not comprehensive. For example, only some of our uakron.edu pages were found, but our uanet.edu pages were not, and my blog not at all. So with care, this is a terrific tool. I am sure it will only get better. At http://rfe.org/rfe_search.php it says there are 12,000 economics web sites and in the link above (http://ese.rfe.org/) over 20,000. Google will do what Google does best -- grow and organize. I added the tool on the right column of my blog so I can get to it quickly.
Thanks for the tool Bill.
