Subject: categories: gr-stacks in the literature

Dear all,

after a bit of searching, I cannot find much in the literature about gr-
stacks, more specifically, charts and presentations thereof reflecting (in a
non-technical sense) the group-like structure. Also, aside from self
equivalences of gerbes and quotients of groups (G/H for non-normal H), I
cannot dream up other "interesting" examples - and these are the opposite ends
of the spectrum I want to consider.

All pointers welcome.
