This work offers its users a convenient form by which to locate dated texts from the Old Babylonian Period which have been published in the Archives Royales de Mari I-XVIII as well as in various periodicals. It includes other texts dated to the same period which were parts of the Chagar Bazar, Tell Taya and Rimah archives. Pre-dating the era of widespread use of spreadsheets, the work takes the form of loose, unbound large-format printed sheets, contained within a paper wallet. Also within the wallet is a 20-page booklet containing an introduction to the work. From the introductory text: "On individual sheets of 22 x 35.5 cm, dated materials have been entered into spaces of approximately 1 sq. cm. Each one of these squares represents one day of one month of a particular year or eponym."
