From the homepage:
Numerous royally commissioned texts were composed between 744 BC and
669 BC, a period during which Assyria became the dominant power in
southwestern Asia. Six hundred to six hundred and fifty such
inscriptions are known today. The Royal Inscriptions of the
Neo-Assyrian Period (RINAP) Project, under the direction of Professor
Grant Frame of the University of Pennsylvania, will publish in print
and online all of the known royal inscriptions that were composed
during the reigns of the Assyrian kings Tiglath-pileser III (744-727
BC), Shalmaneser V (726-722 BC), Sargon II (721-705 BC), Sennacherib
(704-681 BC), and Esarhaddon (680-669 BC), rulers whose deeds were
also recorded in the Bible and in some classical sources. The
individual texts range from short one-line labels to lengthy, detailed
inscriptions with over 500 lines (2500 words) of text.
Besides offering corpuses I and IV, the site has information on Neo-Assyrian history, bibliography, and so forth.
