Baird's is a manual that lists all the national fraternities and sororities and what schools they have chapters at.

If you are in a relatively large college library they often have it in the research section. The official title is "Baird's Manual of American College Fraternities" if you want to search for it (if your school/system has an online catalog).

They haven't put one out for a while because they have gone somewhat downhill (the later editions omit a lot of stuff) and they won't print one until they sell all they have already printed.
