A late copy of an inscription on a bronze statue from Ur, begins “When Anu and Enlil looked with steady favour on Adad-šuma-uṣur, the shepherd who pleased their heart, at that time Marduk, the great lord, named his name as ruler of (all) land[s],” supporting the theory that he reigned in Uruk and Nippur before being appointed by Marduk in Babylon.

The brevity of his reign over Babylon proper also explains the minimal contemporary inscriptions found.
Only sixteen dated economic or legal texts attest to his reign, with just two of them from Babylon, bearing the curious double-dating formula adopted by Adad-šuma-uṣur and his immediate successors.
These are inscribed 7 KAM 3 KAM and 9 KAM 3 KAM, speculated to represent his 27th and 29th years.
Twelve of the extant tablets have provenance from excavation at Ur.
The earliest of these is dated to his 3rd year and records that Šamaš-zēra-šubši had inspected and “plucked” 103 sheep.
Much of the remainder concern cattle, their sale and the legal actions taken to secure recompense for their theft.
The determination of innocence or guilt was often arbitrated by “river ordeal,” a process still poorly understood.
In two documents, the judge was Adad-šuma-uṣur, the šakkanakku, “appointee, governor,” a role similarly adopted by his predecessor Šagarakti-Šuriaš and two other texts feature the same group of miscreants, Abu-ṭābu, Zēru-kīnu and Sîn-pūtu, suspects in three separate cases of cattle rustling.

The cities of Nippur, Dur, Isin and Marad had been sacked by the marauding Elamites under their king, Kidin-Hutran III, and two of these, Nippur and Isin were the subjects of construction work by Adad-šuma-uṣur.
Bricks from Isin were excavated in 1975/76 with a Sumerian inscription recording his work on the Egalmaḫ and also earlier from Nippur recording work on the Ekur (example text pictured).
He had been credited with rebuilding the walls of Nippur in the Walker Chronicle.
