UC Davis' extensive Shields Library numbers nearly 2.5 million volumes, including more than 41,000 periodicals and serials. The library is ranked as one of the 25 best research collections in the nation and its collections in the Humanities, and in French language in particular, are adequate for all but the most specialized research. Volumes not available on campus may be readily and promptly obtained from any of the nine UC campuses through interlibrary loan. In addition, a university bus service provides daily transportation to and from the Berkeley campus 60 minutes away.
