LateX

LateX layouts:
A la ASL(Association for Symbolic Logic)
A laSpringer Verlag (note : for books, the class provided now is "svmono". For the old (?) "CLmono" class click here).
A la Cambridge University Press

There is also the sophisticated memoir class.
And the Simple Thesis class from Melbourne.

For LateX slides : try Beamer.

For Mac users, to manage bibliographies and BibteX files, Bibdesk is very good.
