Intermediate Mongolian (A textbook for Modern Mongolian) (Uralic and Altaic Series Vol. 125) Book

Overall, the best overview of the Evenki languages of Siberia in English. Its advantages are that it's a recent volume, includes new scholarship, and is easy enough to find/purchase. The approach to organization of materials taken by Routledge is also very useful, however, it's not long enough and lacks detail on some of the aspects of the less-common variants of Evenki. This is going to be the standard text and reference for probably a decade or greater, so it should have been more comprehensive'and I say that, yes, even though it is fairly good in its scope, because in places it's lacking in depth.
