Hi,
the current issue of the Signpost (the English Wikipedia's community-written and community-edited weekly news bulletin) contains a section summarizing some recent academic research about Wikipedia:
http://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Signpost/2011-06-06/Recent_...
See also an earlier such overview: http://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Signpost/2011-04-11/Recent_...
In the future, we are planning to publish such surveys of recent Wikipedia research on a monthly basis, in collaboration with the Wikimedia Foundation Research Committee - expect further announcements on this list.
If you know about a newly published academic research paper about Wikipedia that seems worth covering, a tip is welcome at http://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Signpost/Newsroom/Suggestio...
Regards, HaeB
