Are electronic reference books visible in academic libraries? A survey administered to librarians at colleges and universities in the southern United States is used to ascertain the presence and promotion of electronic reference books in academic libraries. Findings reveal that electronic reference books are not as visible in academic libraries (both online and in library buildings) as traditional print reference is. Librarians surveyed indicate they promote electronic reference books more than print reference books. To gain an understanding of what needs more marketing, librarians should examine usage statistics. Librarians should employ a variety of ways to market and promote electronic reference books, and assess which methods work best to reach patrons. In addition, librarians and classroom faculty should work together in collection development and in endorsing the usage of electronic reference books.
