The YIVO Institute for Jewish research announced the recent discovery of 170,000 pages of Jewish manuscripts that Lithuanian librarian Antanas Ulpis hid from the Nazis in the basement of a church. Included in the find are secular books, seforim, and record books of shuls and yeshivos.
A treasure of the collection is a manuscript from Rav Avrohom Dov Ber Kahana Shapiro, the rov of Kovno, who authored the three-volume Dvar Avrohom. There is also a letter written by Rav Eliyohu Meir Bloch about the study of mussar in Telz and other important pieces.
YIVO has saved 1.2 million Jewish documents from Eastern Europe.
