An important and steadily expanding centralized information portal for all aspects of the history and culture of the Sasanian Empire, hosted at the University of California-Irvine, under the direction of Touraj Daryaee.  Some highlights of the site are the open-access series “e-sasanika,” including bibliographical studies, topical surveys, and catalogues of material culture; various primary sources in English translation; a working bibliography of Sasanian studies in the form of a searchable pdf; updates on excavations in Iran; and a searchable numismatic database under construction.  There are also updates on events in Sasanian studies, especially at UC-Irvine; and plans for a blog.
