In search of fresh material for the history of the Saljūqs of ‘Irāq I had the good fortune, during my stay in Istanbul from the middle of September, 1937, till the end of January, 1938, to find and study many MSS., both in Arabic and Persian. I propose to give here a bare inventory of some of these MSS. to bring them to the notice of interested Orientalists, with little or no attempt at scholarly presentation, as my entire time, at present, is occupied with the subject mentioned above. But I hope to contribute a detailed study of the same at a later date.
