Directories are a useful source of names and addresses for the genealogist.
Handbooks and guides are excellent starting points for genealogical research. They can provide general background information on all aspects of the subject, define unfamiliar terms, and offer bibliographies of other sources. If there is an index, it should be used for best access to a subject.
Bibliographies suggest other sources of information, which may or may not be owned by the NMSU library. Books not owned by the NMSU library may be borrowed through interlibrary loan with the permission of the owning library. Non-students should use the Branigan Library interlibrary loan service. Many genealogical books are not available through interlibrary loan, but may be used in person at the owning library.
