Yizkor Book A 1948 event program titled Entertainment and Ball Given by the United Wisoko-Litowsker and Woltchiner Relief is subtitled Yizkor. As a result this publication has become known as the Yizkor Book for Wysokie -- and for Woltchin, also known as Volchin. The publication contains disappointingly little documentary information about the towns. Only a few copies are known to exist. An English translation may be viewed here.
