Treatises (i.e. books) are an especially valuable source for background or in depth research. These publications provide authoritative analysis or commentary regarding the subject matter and often reprint the full text of primary source documents.
In addition to the Law Library & University Libraries online catalog (The CAT), we have access to the other Big Ten university library catalogs, as well. Although the primary focus of some of these library collections is nonlegal, it is likely that they would include some materials relevant to your research. For example, Pattee/Paterno Library at University Park is a U.S. government and European Union depository library and would have a vast quantity of relevant legal material. For the most part, the University Libraries collect heavily in U.S. and international materials. If you are unsure how to use The CAT, one of the librarians will assist you.
