LATEX runs on a variety of computers at many different sites. This document tells you how to use LATEX on the Magic, Lewis, and Clark computers at SRC. It is not about LATEX itself, which is described by the manual—LATEX: A Document Preparation System, published by Addison-Wesley, available at fine book stores everywhere.
If you have a question that you can't answer by reading the manual and this document, ask Leslie Lamport. He should also be informed of any possible LATEX bugs or undocumented anomalies.
