Dear Colleagues,  

I've just finished a survey article entitled
"Groupoids: unifying internal and external symmetry", which I have
submitted to the Notices of the AMS.  It is available as a postscript
file via email ([email-masked]) or my web page
(http://math.berkeley.edu/~alanw).  Comments are welcome, of course.
