Scopus, "the largest abstract and citation database of research literature and quality web sources", can be found at http://info.scopus.com/.
Here is what one of its users, Russ Schmehl (Tulane University, USA), says about it: "Scopus has three main benefits that make it excellent: 1. Literature/author searching is faster and easier. 2. Refinement: You can refine a search by selecting particular authors, years, journals or sub disciplines quickly and easily. 3. Search and report: You can set up Scopus to search for and send citations to you as new published works appear...covering an enormous number of publications."
Representation in databases like Scopus is getting more and more important for academics. My search of its list of periodicals (nearly 18,000 titles from more than 5,000 international publishers) discovered none of the publications that deal with our area as a whole. The closest to that among the journals actually listed in Scopus come Osteuropa, Slavonic and East European Review, South European Society and Politics and Studies in East European Thought. The only subfield which is relatively well represented is "Byzantine and Modern Greek Studies" featuring the journals Byzantine and Modern Greek Studies, Byzantinische Zeitschrift, Byzantion: Revue Internationale des Etudes Byzantines, Greek, Roman and Byzantine Studies and Journal of Modern Greek Studies.
