Latin American science is meant to be open access: Initiatives and current challenges

Latin American open access (OA) initiatives were built upon the foundations laid by the regional cooperative information networks, databases and indexes that started to be developed from the 1970s.

This article summarizes the reasons behind the emergence of OA in the region, offers details and data about the most relevant initiatives and discusses some of the current challenges to keep advancing in this arena.
