For a convenient summary, see D. O. Edzard, “Literatur,” in Reallexikon der Assyriologie, vol. 7, ed. Edzard (Berlin: Walter DeGruyter, 1987), pp. 35–48. Edzard’s figures add up to 19,000 lines, but exclude some large categories such as liturgical hymns, royal hymns, litanies, Dumuzi laments, individual players, literary letters, proverbs and incantations.
