At the Amazonicas V meeting in Belém a couple of months ago, Francesc Quiexalós announced that many recent years of Amerindia, one of the modest number of journals focused on Americanist linguistics, would be made available online. Françoise Rose has recently announced the free availability of issues from 1976-2012 via the CELIA portal, here.
Amerindia, if you are unfamiliar with it, publishes a fair number of articles on Amazonian languages and those of neighboring areas. Paper copies of the journal can be somewhat hard to come by, so the readily availability of many interesting articles via the CELIA portal is welcome news indeed!
