The first two volumes of Amazonian languages: An international handbook are now available. Edited by Patience Epps and myself, these two volumes present grammatical descriptions of all reasonably well-attested linguistic isolates of the Greater Amazonian region. Volume I covers Aikanã to Kandozi-Shapra, and Volume II covers Kanoé to Yurakaré. (A chapter in Volume III will summarize what we know about about the more poorly-attested isolates and small language families known only from colonial-era materials.)
At this time, the freely available material is limited to the front matter and the Introduction to Volume I, written by editors.
The next volumes in the series will focus on the small language families of Greater Amazonia, and the final volumes, on the large language families of the region.
