Cuneiform Akkadian tablets are usually found in the context of larger archives and tablet collections, such as the royal libraries of Assyria (e.g., Nineveh), the administrative archives of Babylonia (e.g., Nippur, Uruk), or the diplomatic and economic correspondence of Late Bronze Age city-states (e.g., Amarna, Ugarit, Mari).

Cuneiform tablets from the Middle and Late Bronze Age have been discovered throughout the southern Levant. For a catalogue of the cuneiform texts from Canaan, see here:
-Western Peripheral Akkadian (Syria)
There are several known cuneiform corpora and archives written in the geographical regions known as the Middle Euphrates, Lower Ḫābūr, and Northern Syria. The most important sites from which these archives derive include, inter alia, Alalaḫ, Aleppo, Ebla, Ekalte, Emar, Harrādum, Karkemiš, Mari, Nuzi, Qaṭna, Tell Šišin, Terqa, Tuttul, and Ugarit.
-Archives from Upper Mesopotamia/Assyria (Northern Iraq)
Similarly, there are several known cuneiform corpora and archives written in Akkadian from Upper Mesopotamia/Assyria. The most important sites from this region include Assur, Chagar Bazar, Kazane Höyük, Qalʿat al-Hadi, Nusaybin, Rimāḥ, Šubat-Enlil (Tell Leilān), Tell Hawa, Tell Tāya, and Nineveh, among others.
-Archives from Lower Mesopotamia/Babylonia (Southern Iraq)
This region represents the heartland of cuneiform culture. The most important sites from this region include Marad, Babylon, Kiš, Dilbat, Lagaba, Tell Egraineh, Sippar in the north as well as Ur, Uruk, Umma, Larsa, Lagaš, Kutalla, Kisurra, Adab, Maškan-šāpir, Isin, Nippur and the Sealand Dynasty in the south. The latitude of Nippur, itself considered a Southern Babylonian city, provides a useful demarcation between Northern and Southern Babylonia, although together these territories can be referred to generally as Lower Mesopotamia (or Babylonia).
