I'm a big fan of mattmight, but I have a problem with the very first book on his list. My academic background is the behavioral sciences, and using MLA will get you in deep dog excrement in most behavioral and social sciences. Our goto style guide is the American Psychological Association's Publication Manual - http://apastyle.org/
APA is predominantly a behavioral and social sciences standard. However, I have a colleague that is currently in a mechanical engineering program and he mentioned just a few days ago that his school has actually gone to exclusively APA for all colleges and departments.
In our humanities grad program we were told to pick either MLA or APA and stick with it. It doesn't matter which, consistency is what matters. Enforcing a particular style across all colleges and departments seems silly. These were the resources we were told to consult:
Anyway, you should have a citations database and whatever citation tool you are using (BibTeX for instance) should be able to pull the citation from the database and format it in one of any number of styles.
It's incredibly rare to find advocates for APA in most humanities fields. I've only come across MLA and Chicago. Was yours a terminal program? Mind sharing the discipline?
The issue isn't so much enforcing a style across colleges/departments as academic journals.
