By publishing this handlist on the occasion of the Snouck Hurgronje
centenary commemoration the Leyden University Library wishes to express
its deep-felt gratitude to that great Arabist and Islamic scholar who
directed our Oriental Library Department as Interpres for nearly 30
years and greatly enriched its collections by leaving us his books and
manuscripts. Up to now only Snouck Hurgronje's Malay manuscripts were
accessible through a printed catalogue made by Prof. dr. Ph. S. van
Ronkel. Now the Arabic manuscripts belonging to his collection and
numbering nearly three hundred, are being made known for the first time
through this list. This is the first catalogue of oriental manuscripts
made by a mem- ber of our library staff. Formerly the task of describing
the oriental manuscripts was entrusted to the Interpres Legati
Warneriani and his helpers, or to specialists among the teaching staff
of the Leyden University or elsewhere. In 1919 the adiutor Interpretis
Dr. C. van Arendonk became a mem- ber of the library staff. He had a
profound knowledge of Arabic liter- ature but, for reasons set forth in
the introduction to this work, he never published a catalogue of the
Arabic manuscripts in his keeping. However, the notes left by him are an
important contribution towards a new catalogue. They have been
extensively used by his successor in compiling this handlist.
