Byzantium's Balkan Frontier: A Political Study of the Northern Balkans, 900-1204
"...Stephenson has incorporated into his work recent sigillographical publications as well as reports on archaeological finds...usefully discussed and analyzed with the help of tables, graphs, and maps of find spots. The book is well written and discussion is concise, and is recommended for all collections."    Choice"...can be lauded both as a successful synthesis of a number of practical, and some theoretical, problems related to Balkan dimensions of the High Middle Ages, and as a thorough new reading of the available written sources, supplemented with overviews of archaeological discoveries made in Southeast Europe during the last decades."
