IV Codices hebraici additi Steinschneider did not include in his catalogue all the manuscript material available in the Library. He did not know of the existence of some items and he disregarded certain others but most of the as yet uncatalogued material consists of later acquisi tions : bequests, gifts, books on loan from other libraries and new purchases. The works unknown to Steinschneider include various kinds of material. There are fragments of manuscripts which were later found in the bindings of other works : a fragment by Kimchi (235-11), one by Maimonides (235-IH), Rashi (238-1), an inter esting Bible fragment (259-1, found in Seal. 4) and a fragment of “Semag” (259-11). They are not all equally important but some are quite old and may provide interesting textual variants. Some material has been found amongst other documents; for instance, a portfolio of assorted “neerlando-hebraica” which contained an autograph letter by the poet Sh. Romanelli (258) or the draft of a letter from Scaliger to the Samaritans (229). Other documents did in fact belong to older collections but had apparently been lost (235-IX in Warn. 73-79; Hebr. 126 in Hebr. 87) «. In the course of the 19th century the Library’s holdings were often enriched by the acquisition of the personal papers of scholars in the fields of Biblical and Hebraic studies. One outstanding example is the extensive legacy of the renowned Schultens family. The collection consists of a large quantity of loose, but well-ordered, papers which bear witness to the huge knowledge and diverse interests of Albert Schultens (1686- 1750) and his son Jan Jacob (1716-1778) and grandson Hendrik Albert Schultens (1749-1793). The MSS Hebr. 127-154 (Or. 1459-1486) are said to have been sold in 1837 at an auction in Groningen and afterwards presented by the king to the Leyden University Library. Thus it is stated in the records of the Department of Oriental MSS but different versions are told 46 a . Hebr. 158 consists of the papers of Egbert Johannes Greve (Deventer 5 Oct. 1754 - 13 Aug. 1811), Professor of Oriental Languages at Franeker from 1795. As a result of the efforts of the Librarian, W. N. du Rieu, Greve’s papers were transferred to the Library on 10 Sept. 1891 from the estate of one of his descendants, a Haarlem clergyman. Greve, who had studied at Deventer and Leiden, was primarily interested in establishing the classical metres in Hebrew Biblical poetry and published books on this subject; on Job 34-42 (vol. I, Deventer 1788, vol. II, Steinfurt 1791) and on Na hum and Habakkuk (Amsterdam 1810.). The library also possesses an interleaved copy of the Van der Hoogt edition of the Biblia Hebraica (Amsterdam-Utrecht 1705) (press-mark 878 D 1-4) which contains Greve’s autograph notes on the poetical passages in the Bible. 45. Hebr. 126 was gifted to the Library in 1888. See note 46. 45». See M. J. de Goeje, Cat. Codd. Or. Bibl. Acad. Lugduno Batava V (1873) pp. 123-7 and J.
