The Journal of Semitic Studies (JSS) is an excellent academic journal that deals with the Semitic languages in detail.
Another excellent resource is Insriptifact, by the West Semitic Research Project at the University of Southern California. It features free high resolution photographs of hundreds of inscriptions and artifacts from the Ancient Near East. The Image below is a portion of an image of a Ugaritic tablet I downloaded from Inscriptifact.
It gives you only a small taste of the clarity and beauty of these images. To use it, you must sign a waiver and fax it to Inscriptifact, but it is well worth it. Thanks to Dr. Bruce Zuckerman for introducing me to this resource.
