FOREWORD The idea of publishing some kind of catalogue of Arabic manuscripts in S.O.A.S. Library is not new. It was first conceived in 1939 when Prof. R.L. Turner was Director and Librarian, and Dr. A.J. Arberry (then Assistant Librarian at the India Office) prepared a handlist of both Arabic and Persian manuscripts, and went some way in correcting copy for the press. However, a number of difficulties seem to have arisen, not least because of the outbreak of war and the actual printing of the text being assigned to Beirut. The project was abandoned in 1950. It is, therefore, particularly pleasing for me that I was able to revive the idea and to make arrangements for a complete catalogue of the Arabic manuscripts with full bibliographical details and appropriate indexes. Although the number of manuscripts has doubled since the earlier attempt, the work has come to fruition in little more than six months. Credit for this accomplishment must go, of couse, to the compiler of the catalogue, Adam Gacek, who first came to the Library in January 1978 to prepare a catalogue of the rich collection of Arabic manuscripts belonging to the King Faisal Philanthropic Foundation. This task, which took some two and three- quarter years and to which he brought considerable expertise and devotion, was completed in Autumn 1980. He then accepted a further commission to undertake the cataloguing for publication of the School's own Arabic manuscripts, and the results of his labours are contained in this volume. The manuscripts embrace a whole range of subject matter, as can be seen from the subect index, and some of them are rare or unique. The illustrations have been carefully chosen to reveal noteworthy examples of calligraphy, embellishment, and binding. It is hoped that the catalogue will be of value to scholars not only within the University of London, but throughout the world.
