I am looking for Albrecht FrÃ¶hlich's unpublished text `Groupoids, groupoid spaces and cohomology' (1965). In this text FrÃ¶hlich 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.
