The new version of the talk in `beamer' class is here in pdf format
My old talk in the `seminar' class: The slides to this version are available in dvi format, postscript, latex source and pdf
The simple latex file is located simple-article.tex
While a more extended version is available talk-article.tex. Also need picture.eps.
You will need the associated my-bibliographic-database.bib if you are to successfully compile these
Leslie Lamport's small2e.tex and sample2e.tex are also available
The local LaTeX information site is located at http://www.it.ms.unimelb.edu.au/tex/index.html
There is a wealth of information on this local site.
In particular,there are two manuals describing the LaTeX language itself, which may at a pinch substitute for a book, a concise manual entitled Essential LaTeX an a fuller "not so short" Introduction to LaTeX2e.
