RePEc (Research Papers in Economics)
http://repec.org/

RePEc (Research Papers in Economics) is a collaborative effort of hundreds of volunteers in 71 countries to enhance the dissemination of research in economics. The heart of the project is a decentralized database of working papers, journal articles and software components. All RePEc material is freely available. You may add your own materials to RePEc through a department or institutional archive — all institutions are welcome to join and contribute their materials by establishing and maintaining their own RePEc archive. If your institution does not yet participate in RePEc, you may submit your own papers to MPRA (the Munich Personal RePEc Archive), and they will automatically be included in RePEc. RePEc does not support personal archives (only institutional archives). RePEc collaborates with the American Economic Association’s EconLit database to provide content from leading universities’ working paper series to EconLit. The RePEc database holds over 945,000 items of interest, over 815,000 of which are available online. This will be added to Academic and Scholar Search Engines and Sources White Paper. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
