The present double volume of the "Catalogue of the Babylonian Tablets" presents all tablets from Babylonia excavated, purchased or donated between 1821 and 1881. Cataloguing of these collections began in 1894-5 when T. G. Pinches prepared a slip catalogue of the first part of the second Spartali collection. The work was continued by Abe Sachs, Donald Wiseman, Irving Finkel and Christopher Walker, supplemented by contributions of several other scholars. Several thousands of cuneiform Tablets now in the British Museum are catalogued providing up-to-date information about their provenance, content and their history of publication: Akkadian as well as Sumerian texts -- administrative and legal texts, as well as letters, royal inscriptions, epics, incantations, omens and other literary texts.
