Over a million records of open access publications from Latin America are now discoverable through the OpenAIRE platform. In December 2016, OpenAIRE began harvesting records from LA Referencia, the large regional repository network that aggregates metadata of open access publications. LA Referencia contains over 1.2 million records of open access content from nine countries in Latin America: Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, El Salvador, Mexico, and Peru. The records provide access to the peer-reviewed journal articles and theses and dissertations in these countries across all research disciplines. This effort integrates the research outputs of the two regions and will significantly raise the visibility of Latin American publications outside the region.
