RePEc now indexes over one million works

RePEc has reached over the last week-end a historic mark: one million works in Economics and neighboring sciences are now indexed, of which 87.5% are available for download. The bibliographic database is comprised by 59.2% of journal articles, 38.5% of working papers, 1.3% of book chapters, 0.8% of books, and 0.2% of software components. All this material has been indexed by volunteers maintaining close to 1300 archives. As RePEc bears no costs, all the data is made available for free.

When RePEc started in June 1997, it built on a stock of metadata with 40,000 entries from its precursor NetEc, which started in 1992. Since then, data holdings have increased in an ever increasing fashion:

The data collected by RePEc is used by a large number of free core services, including EconPapers, EconomistsOnline, IDEAS, NEP and Socionet. Other services that use RePEc data, however without reporting back usage statistics include, among others, Econlit, Google Scholar, Inomics, Microsoft Academic Search, and Worldcat.
