From the SciELO Blog:
The SciELO Program is setting in motion a basic plan for the development and operation of a preprints server – SciELO Preprints.
The main objective is to contribute to speeding up the availability of research results and to position the scholarly communications from the countries that participate in the SciELO Network, and particularly its journals, in line with the advances and growing importance of preprints publication internationally.
