Handwritten diaries and notebooks containing writings on Greek history, Roman mythology, notes from lectures, poetry verses and prose.

Correspondence and papers of Dr Moses Gaster, his family, and the family of his wife Lucy (née Friedlander), 1796-1973, dating largely from the 1870s to the 1930s, also including some material on Gaster's life and work which post-dates his death. Many papers relate to Gaster's activities in his official posts, notably as Haham, to his interests in Jewish affairs and Zionism, and as a scholar, but the collection touches upon a wide range of topics in late 19th and early 20th century history, including the history of Rumanian Jewry and Anglo-Jewry. The bulk of the collection comprises Gaster's correspondence, which includes letters from Jewish and Zionist organisations in Britain, Europe and Jerusalem, from newpapers, periodicals and publishers, and from a large number of individuals outside Gaster's family, including eminent British, European and American Jewish scholars, rabbis and public figures, such as members of the Adler, Gollancz, Mocatta, Montefiore and Rothschild families, and with non-Jewish public figures, but it also includes a wide range of other material.
