What information was recorded on the earliest Sumerian tablets from Uruk?

The earliest written records in the Sumerian language, found on pictographic tablets from Uruk, functioned primarily as administrative aids for an expanding society rather than as records of literature or royal achievements.12

These tablets served as ledgers or lists of commodities, identified by drawings of objects accompanied by numerals and personal names. They also occasionally included information regarding professions. Because these records were highly laconic and intended to assist memory for administrative purposes, they often require knowledge of the specific context to be fully understood.12

The development of this writing system was closely tied to the economic life of the city, including the mass production of standard vessels used for the distribution of rations to the population. Over time, these pictographs evolved into the conventionalized wedge-shaped signs known as cuneiform, which allowed for more complex expression through the use of logograms and phonetic symbols.321
