The collection consists of 15 Babylonian clay tablets; eight of these have been authenticated by Edgar J. Banks and deciphered enough to approximate their subject matter. They are: 1.) Found at Warka, a contract tablet bearing the name of Nergalsharezer (Neriglissar), King of Babylon, 562 B.C., and dated in the second year of his reign, or in 560 B.C.; 2.) Found at Warka, a contract tablet bearing the name of Nabonidus, the last Semitic king of Babylon, 556-538 B.C., and the father of the Biblical Belshazzar, dated in the seventh year of his reign, 549 B.C.; 3.) Found at Warka, a contract tablet bearing the name of Cyrus, the first Persian king of Babylon, 538-529 B.C., the tablet is dated in the seventh year of his reign, 531 B.C.; 4.) Found at Warka, a contract tablet bearing the name of Cambyses, son of Cyrus, King of Babylon, 529-522 B.C., and dated in the second year of his reign, 527 B.C.; 5.) From Drehem, the tablet was first written and then sealed with a cylindrical seal to prevent any alteration in the writing; 6.) From Drehem, a list of objects presented to the temple; 7.) From Drehem, it is a part of the temple records of that city and related to objects presented to the temple for sacrificial purposes, it comes from one of the early kings of the Ur dynasty; 8.) From the temple at Johka, a part of the temple records, it is dated on the bottom edge. The other tablets are as of now undeciphered, but still form an interesting record of a vanished culture.
