The Best Of Isaac Asimov

Although not an author whom average readers would associate with mysteries, Asimov has actually written several good ones. This collection contains 31 short pieces that are among his personal favorites. Two sections contain his series stories, the ''Black Widower'' and the ''Union Club'' mysteries. Brief introductions to each section and story will serve to acquaint readers with the general background of the series. A third section contains miscellaneous mysteries. All are clear and entertaining. This is a book to be read on ''a little here, a little there'' basis. The stories are short, and prolonged reading results in a series of mental stops and starts that are wearying. Also, the stories are written according to a set formula. However, read on the installment plan, the book is worth the effort. If the recent spate of series in juvenile publishing is any guide, this collection should please adolescents, including reluctant readers. Karl Penny, Houston Public Library
