   Format: MarkdownItexadded pointer to * [[Alan Weinstein]], p. 6 of: _Groupoids: Unifying Internal and External Symmetry -- A Tour through some Examples_, Notices of the AMS volume 43, Number 7 (1996) ([pdf](http://www.ams.org/notices/199607/weinstein.pdf), [[Weinstein_Groupoids.pdf:file]]) Is there an citable account with more introduction/exposition along the lines of Weinstein's p. 6? I am looking for something one can hand to the educated layman for them to get an idea of what topological groupoids are (i.e. no stacks, no internalization, no technical proofs, but a good feel for the topic.) While I was at it, I also added pointer to: * [[Carsten Butz]], [[Ieke Moerdijk]], *Representing topoi by topological groupoids*, Journal of Pure and Applied Algebra Volume 130, Issue 3, 17 September 1998, Pages 223-235 (<a href="https://doi.org/10.1016/S0022-4049(97)00107-2">doi:10.1016/S0022-4049(97)00107-2</a>) <a href="https://ncatlab.org/nlab/revision/diff/topological+groupoid/10">diff</a>, <a href="https://ncatlab.org/nlab/revision/topological+groupoid/10">v10</a>, <a href="https://ncatlab.org/nlab/show/topological+groupoid">current</a>
