The Sumerian šu-il-la is an Emesal composition which,like the balag and ér-šèm-ma, was utilized in public worship. Forty-seven šu-íl-la incipits are listed in the kalûtu catalogue IVR 53 + RA 18 (1921), 158f., but the broken state of the catalogue and the poor state of preservation of the majority of Emesal texts makes it impossible to identify most of the catalogue entries. Only three surviving texts can be identified with certainty—by their colophon or presence in the catalogue or both—as Sumerian šu-íl-la's:
A. Sjöberg Mondgott 166ff. Sin; incipit IVR 53 iii 48
F. H. Weissbach Misc. pl. 13F. and duplicates Marduk; incipit IVR 53 iii 54 (edited below).
RAcc. 70f. and 108ff. An; the beginning is broken, so that it cannot be ascertained whether this is the šu - í l - la to An whose incipit is listed in IVR 53 iii 44
The last two contain subscripts specifying the cult occasions upon which they were to be recited. Four additional fragments can probably be classified as šu-íl-la's because of their extensive parallels to the Sin and Marduk šu-íl-la's (see below).
Unlike the balag and ér-šèm-ma, the šu-íl-la was never organized into long liturgical compositions, but the individual šu-íl-la's collected in Ashurbanipal's library were arranged within the library in a fixed order, corresponding to the order in which they were listed in the catalogue IVR 53. This can be shown by the fact that the catch line of the Sin šu-íl-la (as preserved in IVR 9) is identical to the incipit which follows the incipit of that Sin šu-íl-l a in the kalûtu catalogue.
