E-books are now an integral part of the collections in academic libraries. This paper explores current restrictions on viewing, printing, downloading, circulation, and inter-library loan. It also covers how these affect the lending of mobile devices and library e-readers. Restrictive licensing clauses, proprietary software and file formats, digital rights management (DRM), and the single-user business model many e-book publishers use are the most significant issues. In many academic libraries, the allocation of funds for marketing has been overlooked. Many librarians have created promotional activities at minimal cost to the library.
