LaTeX is available on CSLab, RCS, and probably most other campus computers. To download a LaTeX system (free) for use on a Windows PC, visit
I recommend the following manual:
Leslie Lamport, LaTeX: A Document Preparation System User's Guide & Reference Manual, Addison-Wesley, 1986, ISBN 0-201-15790.Borders or Barnes and Noble should have it, or try online at Amazon or Bookpool (usually cheaper but less likely to have it in stock).
