Some institutions offer master's degrees only, while others offer doctorates in selected fields. Major research universities offer master's degrees and doctorates in a wide range of fields. There are many general guides to graduate programs. Most college and university libraries and career centers and many public libraries will have at least some of these publications. College libraries, counseling or career centers, and admissions offices generally maintain collections of college and university catalogs.
Web sites are also easily accessible for most institutions.
You will probably have certain personal preferences regarding the kind of institution you attend. Size and location are two factors that often influence a person's decision about where to go to school. There are advantages to both large and small institutions. Location is important if you believe you cannot make a major move because of personal or family concerns. The most important factor should be how well the graduate program of an institution fits your particular interests, academic background, and goals.
