The Ugaritica volumes are now online at the Archive of Mesopotamian Archaeological Site Reports (AMAR) website. The Ancient World Online has the most convenient links to the individual volumes. But do browse around the AMAR site. They have many important publications.
While generally thought of as excavation reports from Ras Shamra – and they are that -, a couple of these volumes contain the original publication of some of the most important Akkadian and Ugaritic tablets from Ugarit. There have been long stretches of my life, both recent and past, where a day did not go by without my having consulted Ugaritica volume V.
