Here are the example files from the talk I gave Friday, October 27.
If you plan to use TeX very much at all, you should definitely pick up a copy of Donald Knuth's "The TeXbook", and, for LaTeX, a copy of "LaTeX: A Documentation Preparation System", by Leslie Lamport. Both should also be available at the library. The former is also available on line (see below), but you'll want a hard copy too (trust me).
