The Darkover Concordance

The Darkover Concordance is a 164-page resource to Marion Zimmer Bradley's books. It has the subtitle, "A Reader's Guide." It was written by Walter Breen, and has a foreward by MZB. It contains diagrams, art, and articles. It was originally to be published by T-K Graphics but in Darkover Newsletter #13/14, MZB writes that the publisher "bitten off more than he could chew," was in financial ruin, and had returned the manuscript to Walter Breen. It was then published by Pennyfarthing Press in April 1979.
