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.
This edition, representing 956 libraries and 156,449 titles, incorporates the 2nd ed. (1943) and its two supplements together with new titles and additional locations.
In Ibāḍī Texts from the 2nd/8th Century Abdulrahman Al-Salimi and Wilferd Madelung offer an edition and detailed historical analysis of religious letters by early Ibāḍī leaders in Basra, Oman, and Hadramawt.
