The established reference work Guide to Reprints has been radically reworked for this edition. Bibliographical data was substantially increased where information was obtainable. In addition, the user-friendliness of Guide to Reprints was raised to the high level of other K.G. Saur directories through author-title cross-references, a subject volume, a person index and a publisher index. In this edition, the directory lists more than 60,000 titles from more than 350 publishers.
