This research aims to examine whether faculty's perceptions of the importance of the library's resources and services for their teaching, clinical practice or research were different based on disciplines, and to explore the degree that faculty's perceptions of the library's importance and its role have changed over time. The findings revealed that online journals, databases, and Interlibrary loan (ILL) were considered by the majority of faculty as the most important for faculty's research. Another key finding indicated that faculty from social sciences perceived assistance from a subject specialist librarian as more important than faculty members from physical sciences. The top three strategies faculty use to obtain articles not available through the university include searching for a freely available online version, using ILL, and obtaining it from Google Scholar. These findings assist the library to better understand our user community's needs. As this survey is regularly deployed, it also allows us to observe potential changes over time, and as necessary, make strategic changes to library resources and services.
