This is a two-volume collection:

o Austin Problems in Mathematics (APM)

  The problems that have been on past prelim exams administered by
  the math department at the University of Texas at Austin.

o APM Cross-Index (APM-Xi)

  A reference work, indexing the problems according to the
  appearance of various keywords and containing many of the relevant
  definitions and alternate meanings for these keywords, as well as
  many supplementary definitions and proofs.

I hope to expand the APM into a full solution guide, (cf. Berkeley
Problems in Mathematics, published by Springer).  But I don't think
I can do this alone, certainly not any time soon.  Indeed, I am
currently looking for someone to take over maintainership for this
work, although I would be happy to continue to contribute as time
permits.

(Note, this page used to advertise "Austin Problims in Mathematics".
Stellar typo, huh?  Then, for a while, "Austin Prelims in
Mathematics".  But the real title is "Austin Problems in
Mathematics", just like the Berkeley book.)
