Since more than 240 organizations and individuals have put their economic working on the Internet, it is no longer practical to list each site here. Rather, you should check with the the sites listed here that specialize in working papers. The first, WoPEc, is a database of working papers on the net. Thus, it simply collects bibliographical material on working papers at different sites.
Users can query it to locate papers.
Currently, WoPEc lists more than 4,000 papers. The second is EconWPA, which puts up papers for those who don't wish to run a site. It is the single largest collection of working papers in economics. Information on papers in EconWPA is automatically included in WoPEc. Those who run working paper sites should be sure that information on their papers is included in the WoPEc database.
