If your journal publishes in economics, finance, management or a neighbouring social science, RePEc is probably the single most cost-effective indexing service you can join: it is free, it is used daily by economists worldwide, and its data feeds a long list of other discovery platforms. The catch is that RePEc does not crawl your website. It expects you to publish structured metadata files, in its own format, on your own server — and to keep them accurate with every new issue.
This article explains what RePEc is, what an OJS journal gains from being listed, what a RePEc archive actually consists of, and where the setup tends to fail.
What RePEc is
RePEc (Research Papers in Economics) is a decentralised, volunteer-run bibliographic initiative covering economics and related fields: journal articles, working papers, books, chapters and software components. According to repec.org, the project has no central budget — publishers and institutions supply the data, sponsor organisations supply the infrastructure, and every service is free for readers, authors and publishers alike.
The model is deliberately simple. Each participating publisher keeps a set of plain-text description files on its own server. RePEc services fetch those files on a regular schedule, usually daily, and merge them into the public databases.
The scale, as reported on repec.org: more than 2,400 archives across 106 countries, over 5.5 million items, from 4,600 journals and 5,900 working-paper series, with over 74,000 authors registered in the RePEc Author Service.
Why it matters for a journal
Being listed in RePEc does four things for a journal.
It puts your articles where economists search. Content becomes browsable and searchable on IDEAS and EconPapers, the two main RePEc front-ends, and new items are pushed out through NEP (New Economics Papers), an e-mail and RSS alert service organised into more than 90 subject fields.
It propagates to other platforms. RePEc bibliographic data is in the public domain and is reused by external services. Repec.org lists EconLit, Google Scholar, OpenAIRE, EBSCO, OpenAlex, ResearchGate and WorldCat among them. One correctly maintained archive therefore feeds several discovery channels at once.
It produces citation and usage metrics. CitEc extracts and links citations between indexed items; LogEc reports abstract views and downloads. Both feed the RePEc rankings of authors, institutions and publications that many departments follow closely.
It connects authors to their work. Researchers registered in the RePEc Author Service get a profile that automatically claims their articles in indexed journals and notifies them of new citations. For a journal, this is a recruiting argument: authors increasingly prefer venues where their papers show up in their RePEc profile without extra effort.
What a RePEc archive consists of
The official step-by-step tutorial on ideas.repec.org describes six stages:
- An archive code — a three-letter identifier issued by the RePEc team on request. Archives are institutional, not personal; a publisher with several journals runs one archive with one series per journal.
- A public directory on your server, reachable over HTTP, HTTPS or FTP, where the metadata files will live.
- An archive template describing the publisher: name, URL, maintainer contact.
- A series template for each journal: title, ISSN, publisher, homepage.
- An item template for every published article: title, authors and affiliations, abstract, keywords, JEL codes, year, volume, issue, pages, DOI and the URL of the full text.
- A notification to the RePEc team that the archive is ready to be harvested.
All of these are written in ReDIF (Research Documents Information Format), a plain-text format that is easy to read but strict about field names, character encoding and complete URLs. A single malformed file can stop the harvester from picking up an entire series.
Automating it in OJS — and where it goes wrong
Writing ReDIF templates by hand is manageable for a handful of issues and unsustainable after that. For Open Journal Systems there is a dedicated module, available in the OJS plugin gallery, that generates the ReDIF files from article metadata and regenerates them whenever an issue is published or a record is edited.
Installing the module is the easy part. In practice, three things decide whether a journal ends up properly indexed or only nominally so:
- The RePEc identifiers. The archive code has to be requested and the series codes assigned consistently across journals; mistakes here surface only after the first harvest.
- The metadata already in OJS. Journals with a large back catalogue routinely have missing abstracts, inconsistent author affiliations, absent JEL codes, and DOIs or ORCID iDs that were never entered. The module exports what it finds — it does not fix it.
- Validation before notifying RePEc. The generated files need to be checked for syntax and reachability from outside the server before the archive is announced.
Skip these and the likely outcome is a journal that is “in RePEc” with half of its articles missing and authors whose profiles never link to their papers.
What we do for OJS journals
OJS International delivers RePEc indexing as a complete service: requesting the archive code, preparing the public directory on our OJS hosting or on the journal’s own server, installing and configuring the module, auditing existing article metadata, generating and validating the ReDIF files, and notifying the RePEc team. For journals with a large archive, the metadata clean-up is handled as part of our content migration to OJS service, and editorial teams receive, through training and consulting, the metadata rules that keep future issues indexable. Where a journal’s theme or workflow needs adjusting to expose the right fields, that falls under OJS customization.
Journals we manage are listed in our portfolio, and you can explore the platform first in our OJS demo environment.
Frequently asked questions
Does RePEc charge for indexing? No. RePEc is free for publishers, authors and readers. The only cost is the technical setup and the ongoing upkeep of metadata.
Can any journal be indexed in RePEc? RePEc covers economics and adjacent disciplines — finance, management, economic statistics, and social sciences with an economic component. Journals outside that scope are not accepted.
How long until articles appear on IDEAS and EconPapers? Once the archive has been announced and accepted, RePEc harvests the files automatically, usually daily. Initial inclusion depends on the RePEc team’s response; subsequent updates typically show within days.
We publish three journals. Do we need three archives? No. One institution runs one archive, with a separate series for each journal.
What happens if we edit an article’s metadata after publication? The module regenerates that article’s ReDIF record and RePEc picks up the change on its next visit. Deletions propagate the same way.
Is RePEc an alternative to DOAJ or Crossref? No, it is complementary. Crossref registers DOIs, DOAJ certifies open-access practice, and RePEc indexes and distributes content to the economics community. A well-positioned journal has all three.
Conclusion
For an economics journal on OJS, RePEc indexing is a small effort with a network effect: one correctly configured archive feeds IDEAS, EconPapers, NEP, CitEc and every external service that reuses RePEc data. The condition is that the ReDIF files are generated from clean metadata and kept current — which, with the right module and a proper audit, happens automatically.
If your journal publishes in economics and is not yet in RePEc, or is listed but no longer updating, we can take the setup from archive code to first harvest.
