Book excerpt: A new edition of the who's who of over 1,400 fictional characters whose names are sometimes so familiar it's difficult to remember they're imaginary. Included in the biographical parade is Ben Casey, Casper, and Fitzwilliam Darcy, a compendium of high, low, and no brow at all, each exactly recorded with a snippet of biographical anecdote. The reference is as equally useful for scholarly work as it is for killing time in aimless pursuits of information. Distributed by Ashgate. Annotation copyright by Book News, Inc., Portland, OR
