A major re-examination of the scrolls was therefore undertaken by the University of Southern California's West Semitic Research Project, using advanced photographic and computer enhancement techniques which enabled the script to be read more easily and the paleography to be dated more confidently. The results confirmed a date immediately prior to the destruction of Jerusalem by the Babylonians in 586/7 BCE. Kyle McCarter of Johns Hopkins University, a specialist in ancient Semitic scripts, has said the study should "settle any controversy over date of these inscriptions".
