Following the successful publication of the first two volumes of Hebrew Bible Manuscripts in the Cambridge Genizah Collections, the substantial process of describing the MS fragments is now complete. These third and fourth volumes present a comprehensive catalogue of the Hebrew Bible fragments in the Taylor-Schechter Additional Series, describing in detail an impressive tally of 14,679 items. Besides the identification of the exact content of each fragment, the volumes contain thorough physical and linguistic descriptions, as well as notes on additional features of interest. Addenda and corrigenda for the previous volumes are included in Volume 4. A canonical index, compiled by biblical book and chapter, provides easy searching of relevant fragments. Taken together, these four volumes now provide the researcher with data on all 24,260 biblical fragments in the Cambridge Genizah collections and will be an indispensable tool for those with special interests in Hebrew Bible, Jewish Studies and Semitics.
