This article aims to provide a practice oriented overview of the current situation of commercially sold or fee-based e-books from the perspective of academic libraries. Given the expectations which both users and libraries hold for this relatively new form of electronic media and the potential which e-books are presumed to have, this article sheds light on what has actually been achieved so far. This survey covers not only a general assessment of the market, but also the current options for access, the price levels and purchase conditions, methods of distribution, options for research and use, and methods of indexing and cataloguing. The essay concludes with examples of actual experiences with e-books in academic libraries and an outlook on possible future developments.
