I am looking for Albrecht Fröhlich's unpublished text `Groupoids, groupoid spaces and cohomology' (1965). In this text Fröhlich defines cohomology of a group with coefficients in a groupoid (this was later generalized by Ronald Brown to cohomology of a groupoid with coefficients in a groupoid). I would be grateful if someone could put this text on the Net.

$\begingroup$ Why are you looking for it? Maybe there is a substitute if you have a specific topic you're looking for. $\endgroup$– user36938Commented Jul 29, 2013 at 7:40

$\begingroup$ @S.Carnahan: I was inspired by the question mathoverflow.net/questions/54402/… on Deligne's letter to Piatetskii-Shapiro. Users answered by scanning and uploading the Russian translation and the English original, and no one complained... $\endgroup$– Mikhail BorovoiCommented Jul 29, 2013 at 11:02

1$\begingroup$ Sorry, I should have explained my misgivings, and now I have forgotten what they were. I think I was concerned about publishing unpublished work without the author's permission, but that does not seem to be particularly relevant in this case. $\endgroup$– S.
