e-Reference books, the challenge of new editions

The new issue of Booklist is out and contains an Off The Shelf column, “The Challenge of New Editions.”  In the article I discuss the realities of updating new editions of reference books in an online environment.  Continuously updated database, new editions, access to multiple editions, and weeding e-reference books are discussed.  Content for the article was obtained from a survey of reference publishers in March 2011.  Other Off The Shelf columns are available on the publications page.
