Redalyc (Red de Revistas Cientificas de America Latina y el Caribe, Espana y Portugal) is a non-profit open-access platform and index for Ibero-American scholarship, operated by the Universidad Autonoma del Estado de Mexico (UAEM) in Toluca. The project began at UAEM in 2002 and the portal went live in 2003, built on a simple premise: research produced in Latin America, the Caribbean, Spain and Portugal was badly under-represented in the mainstream commercial indexes, and needed an infrastructure of its own.

Redalyc is not a publisher. It does not commission, peer review, or own the journals in its collection. It indexes, hosts full text, marks up articles in XML JATS, and distributes them - so you submit to a journal that Redalyc indexes, not to Redalyc itself. As of 2026 the platform reports roughly 1,825 journals, about 770,000 full-text articles, some 839 participating institutions, and content from 36 countries. Everything is free to read and free to publish: Redalyc is a diamond open-access infrastructure, with no article processing charges anywhere in the collection.

AmeliCA (Conocimiento Abierto para America Latina y el Sur Global) launched in 2018 with support from UNESCO, CLACSO and Redalyc as a communally-owned alternative to APC-driven open access. Redalyc supplies much of AmeliCA's technical backbone - the XML JATS pipeline, the markup tools, the metadata layer - and the two have since extended their scope beyond Latin America toward the wider Global South. Redalyc/AmeliCA has been recognised as a SCOSS-supported open-science infrastructure, which is how a good deal of its non-UAEM funding reaches it.

You publish in a Redalyc journal, not to Redalyc. The practical route:

1. Find the journal. Search redalyc.org by discipline, country or title. Each journal page lists scope, ISSN, publisher institution and the journal's own site.
2. Follow the journal's own instructions. Submission systems vary - many hosted journals run Open Journal Systems (OJS); others use email or a bespoke platform. Redalyc imposes no submission workflow of its own.
3. Write in the journal's language. Spanish and Portuguese dominate the collection, with a substantial English-language minority; many journals accept and encourage abstracts in more than one language.
4. Expect no fees. If a journal indexed in Redalyc asks you for an APC, treat that as a flag and check the journal's own fee statement.
5. Peer review is the journal's. Models vary by title; double-anonymized review is the regional norm across the social sciences and humanities.

Journals apply to Redalyc and are assessed against a published set of editorial-quality criteria - regular and punctual publication, a functioning editorial board and peer-review process, ISSN and stable metadata, clear author guidelines, ethics and licensing statements, and demonstrable scholarly content. Inclusion is a review process, not automatic registration, and journals can be removed if they stop meeting the criteria. Redalyc also runs Marcalyc, a free XML JATS markup tool used by more than a thousand editorial teams to produce standards-compliant, machine-readable articles.

The overlap between Redalyc and SciELO is large; plenty of journals are in both. The difference is emphasis: SciELO is organised around national collections and a shared publishing platform, while Redalyc is a single centralised collection with an unusually strong investment in article-level XML markup and metrics.

Cite the journal, not the platform. Give authors, year, article title, journal title, volume, issue and pages exactly as you would for any journal article, then add the DOI if the journal assigns one; if it does not, the stable Redalyc article URL is an acceptable locator. APA, Vancouver and ABNT are the styles most often requested by journals in the collection, but follow whatever your target journal or institution specifies. Do not list "Redalyc" as the publisher.

Most Redalyc content carries a Creative Commons licence, commonly CC BY-NC-SA, though the licence is set by the individual journal - check the article page before reusing. Redalyc exposes metadata for harvesting and its records are picked up by Google Scholar and other discovery services. Individual journals may separately be indexed in Scopus, Web of Science, SciELO, DOAJ or PubMed; being in Redalyc says nothing either way about those, so check a specific title if indexing matters for your assessment.
