Brad Johnson: LaTeX

General Resources
LaTeX Project Page	General information about LaTeX including documentation for beginners.
CTAN	The Comprehensive TeX Archive Network — the ultimate repository for all things Tex and LaTeX.
Text Processing with LaTeX	A nice LaTeX site courtesy of the Department of Engineering at the University of Cambridge.
LaTeX Primer	Another nice LaTeX site courtesy of Dr. David Wilkins in the School of Mathematics, Trinity College.
Windows Specific Resources
MiKTeX	This as a Windows version of TeX and LaTex. You can download the installer from this site. MikTeX does not include a front end. You have a few options: LEd (LaTeX Editor) is a nice (free) IDE for LaTeX under Windows. TeXnicCenter (free, see here also). WinShell for LaTeX (free). WinEdt (shareware). Get a good text editor and create your own. I have not used the first four so I cannot make specific recomentations.
Macintosh Specific Resources
MacTeX	The distribution of choice for Mac's seems to be the MacTeX distribution which includes TeX-Live, TeXShop and many other goodies. A large disk image (dmg) which installs everything is also available here.
Presentation Resources
pdfscreen	A simple but effective tool for making PDF presentations for computer projection.
ifmslide	A little more complicated than pdfscreen but more powerful as well.
The Beamer class	A very nice presentation class.
