These are a collection of brief supplements that I have published on my university website (https://web.mst.edu/~stutts/) over my career since 1992.  They are not peer-reviewed, but I have updated some of them over the years in response to comments I've received.  At least one has been cited in archival peer-reviewed literature, and I continue to receive positive comments via email regarding many of my supplements and examples. 

As always, caveat emptor!  While everything I've posted represents my best efforts, made in the time available, I offer no warranties or guarantee of the accuracy or usefulness of anything I post!
