Dear Reader,
since the 50th Meeting in Kazan 2007 so far did not result in a volume of Proceedings, I decided, in analogy to the Meetings of Tashkent, 1986, and of Huhhot, 2009, to publish the references given in the volume of abstracts distributed at the beginning of the meeting. A sizable number of the 160-odd abstract are quite detailed, and a fair number of them can be considered a full-length paper. See Kazan and the Altaic World.
