On the quincentenary of Spain's expulsion of the Jews, an important but seldom analyzed event in European history, Strom ( The Last Jews of Eastern Europe , Philosophical, 1986) offers a pictorial study of the remnants of this once-dominant Sephardic culture, now relegated to far-flung communities established by the exiles and their descendants. The photojournalist toured Mediterranean Europe and Turkey to obtain his pictures, which he groups by nation and city, introducing each with an essay on the general history of the Jewish community in that location. Unfortunately, he adds few personal observations or details about the subjects he photographed. The result is as uninvolving as a stranger's vacation album: a series of unfamiliar buildings, cemeteries, and people needing elucidation. What should have been a fascinating work proves instead a mildly interesting curiosity. Not a necessary purchase.-- Rose Cichy, Osterhout Lib., Wilkes-Barre, Pa.
