Quaderni di Archeologia della Libia is a journal going back to the 1950s which publishes the results of various types of archeological fieldwork and research concerning places now in Libya. Most articles are in Italian, but some are in English and other languages. As it does not seem to have its own website, I have taken the liberty of posting a link to a list of contents online.
Table of Contents (Issues 1-18) in text format.
Furthermore, most issues (they are not cheap!) can be purchased at the website of the publisher, L’Erma di Bretschneider.
