The Roma, as the Gypsies call themselves, have a long tradition in Eastern European culture -- influencing the music, foods, religious and folk traditions. This is an excellent book on the evasive subject of Roma culture in Eastern Europe, painstakingly researched by Ms. Fonseca as she traveled and lived among Gypsies. Black-and-white photos help give a human face to the conditions of the Roma, their history among the settled peoples of Poland, Czech Republic, Slovakia and Germany and the prospects for their cultural survival in the "new" Eastern Europe.  (EUR09, $14.95)
