From a recent study of university libraries. There’s plenty in this report on digital scholarship, print journals, and comparative approaches of the various disciplines.

Neither faculty members nor librarians expect e-books to constitute a viable substitute for print books; they are more generally seen as complementary.

Somewhat oddly given this low level of faculty interest in e-books, many librarians consider the provisioning of e-books an important role, and substantially more expect it to be one in five years (see Figure 16). This enthusiasm is notably higher at the largest institutions, with one-quarter of librarians anticipating a transformative role and two-thirds believing that licensing and making available e-books is an important library function, both numbers well above those of smaller schools. Librarians’ enthusiasm in the face of a relative lack of interest from faculty may indicate that librarians are responding to student demand or expecting future faculty demand.

It is also possible that librarians believe wider use of e-books will improve their ability to provide library services in a cost-effective manner, and are interested in driving the transformation of the book medium.
