Hi Piotr!
I added you links to
http://meta.wikimedia.org/wiki/Talk:Research/Social_Research_Collaborations
You probably know
http://bibliography.wikimedia.de. Do the categories
(
http://meta.wikimedia.org/wiki/Wiki_Research_Bibliography#Categories)
fit your needs? I could not participate in Wikimania :-( Which of the
many talks and papers at the event do you regard as scientific so I can
include them in the bibliography?
Greetings,
Jakob
P.S: At August 23th I'll give a workshop on Wikipedia Research in
Odense, Denmark. There is still possibility to participate:
