Jewish Gen: Yizkor Books
Yizkor books, each a memorial to a specific town's Jewish community, are collections of history, pictures, memories, and names. These books are relatively hard to find, so Jewish Gen has worked to make them more accessible by placing a few translations online, created a database to search for these books, and created a list for libraries and bookstores who have them.
