A part from a few brief notes of a general nature, the Marsden manuscripts were first described in any detail as a collective whole, by Father H. Hosten, S.J., in the Journal of the Asiatic Society of Bengal, August, 1910 (New Series, vol. vi, No. 8, pp. 437–461) from material supplied to him by Messrs. Philipps and Beveridge. With the transfer of the most valuable portion of William Marsden's magnificent Library from King's College to the School of Oriental Studies in 1918, the Marsden MSS., both those in the British Museum and those now in the School, formed the topic of two articles in the Bulletin of the S.O.S.—the first by Sir Denison Ross in vol. ii, pp. 513–538 (1923), and the second by Father Hosten, S.J., in vol. iii, pp. 129–150 (1925). A few years later Sir Edward Maclagan, who had already published some documents in extract in the JASB. for 1896, catalogued those dealing with Northern India and Bengal amongst the Letters and Reports which he listed on pp. 369–388 of his standard work, The Jesuits and the Great Mogul (London, 1932).
