The Library Journal has partnered with Gale to conduct a joint study of how academic librarians feel they are servicing their faculty clientele, and the results are interesting.
A summary from Inside Higher Education: “Virtually every librarian surveyed, or 98 percent of those respondents, said they wish for better communication with faculty, while not even half of surveyed faculty members, or 45 percent, said the same. About one-quarter of faculty members, or 27 percent, said they don't believe cooperation is necessary at all.”
You can see the Library Journal’s post here which provides a link to the full report and explains the methodology of the research.
Gale’s Blog has a nice infographic outlining the key findings of the survey.
