“The dark side of open access in Google and Google Scholar: the case of Latin-American repositories”…

“the [study of the] presence and visibility of [a total of 137] Latin American repositories in Google and Google Scholar […] indicate[s] that the indexing ratio is low in Google, and virtually nonexistent in Google Scholar [with] a complete lack of correspondence between the repository records and the data produced by these two search tools.”

JURN is doing much better, in that regard, with a little help from Red Federada des Repositorios (which is comprehensively indexed by the main Google) and the general ‘open everything’ attitude to publishing scholarship in South America.
