IDEAS, LogEc, EconLit.

This article highlights several implementations of the Research Papers in Economics (RePEc) archive, which is being implemented with different features by talented economists and programmers in many countries as varied as Sweden, Russia, Britain and the U.S. IDEAS is one of the many excellent implementations of the RePEc collection of free abstracts for more than 200,000 journal articles, working papers, books, book chapters and software. Over half of the abstracts have links to the full-text digital version. The other pick is a spectacularly well-implemented bibliometric service that delivers very informative statistics about the papers, journals, series and authors in RePEc. The pan is the American Economic Association's EconLit database, which is widely licensed by many college libraries and research centers, but is becoming increasingly less and less state of the art. The popularity of the RePEc archive and its services is superbly illustrated by the LogEc service, run by Sune Karlsson at the Economic Research Institute of the Stockholm School of Economics, which analyzes the server logs of the participating RePEc servers. EconLit is produced by the American Economic Association and available on many commercial online services, including CSA, Dialog, EBSCO, OCLC, Ovid, Science Direct and Silver Platter.
