onomics) is a collaborative effort of hundreds of volunteers in101 countriesto enhance the dissemination of research in Economics and related sciences. The heart of the project is a decentralized bibliographic database of working papers, journal articles, books, books chapters and software components, all maintained by volunteers. The collected data are then used in various services that serve the collected metadata to users or enhance it.

So far, over 2,000 archives from101 countrieshave contributed about 2.8 million research pieces from 3,200 journals and 5,000 working paper series. Over 55,000 authors have registered and 75,000 email subscriptions are served every week. See below on how you can be part of this initiative.

The following are services that use (principle) and contribute RePEc data. They also report usage statistics that can be used towards the RePEcrankings.

The RePEc bibliographic data is in the public domain and thus used by other services as well. The following are the ones we know of, and unfortunately none report usage statistics back toLogEc.

The basic principle is that publishers index their content themselves into RePEc. They host the metadata on their http or ftp site, following theGuildford Protocol, which indicates how the metadata archive should be structured. Then, the syntax of the metadata template syntax is guided byReDIF, the Research Documents Information Format.

If you intend to contribute information about your publications to RePEc, you may read the above documents or use thesestep-by-step instructionsorsample templates. The same instructions apply for commercial publishers or research institutes.

RePEc archive maintainers may also make good use of thetemplate syntax and link checker, oftips and tricksand theFAQ.

RePEc is entirely based on the contributions of volunteers: Maintainers of RePEc archives, editors atNEPandMPRA, andthose who runthe various RePEc services. If you want to get involved check out ourvolunteer opportunitiesor contact any member of theRePEc team.

TheArchEcproject provides long-term archiving of RePEc templates and full-text files, with the support of theFondation Banque de France.

RePEc emerged from theNetEc group, created in 1992, which received support for its WoPEc project between 1996-1999 by the Joint Information Systems Committee (JISC) of the UK Higher Education Funding Councils, as part of its Electronic Libraries Programme (eLib). RePEc was created in June 1997 to decentralize the work done by WoPEc and thus make it independent of grant needs. RePEc is then guaranteed to remain free for all parties.

Each RePEc service has contact details; for any question, please email them. For general enquiries about RePEc, in particular toopen a RePEc archive, contactKit BaumorChristian Zimmermann.
