Libāya was the forty-ninth ruler of Aššur according to the Assyrian King List [http://oracc.museum.upenn.edu/riao/kinglists/assyriankinglist/assyriankinglist/index.html#BelubaniDynasty] (AKL). After succeeding his father Bēlu-bāni [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/belubanidynasty/belubani/index.html], Libāya held power for seventeen years; he was followed on the throne by his son Šarma-Adad I [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/belubanidynasty/sharmaadadi/index.html]. J. Reade suggests that Libāya and his son, like his father Bēlu-bāni, may have been either independent rulers of the city Ekallātum or were governors of Aššur who were dependant on the more powerful Ekallātum; thus, Libāya and Šarma-Adad I may have been contemporaries of Bāzāyu [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/belubanidynasty/bazayu/index.html], a man whom the AKL states was a son of Bēlu-bāni who exercised kingship for twenty-eight years.
