My great grandfather learned in many big European yeshivos.
I recently obtained from his nephew 7 notebooks he wrote of shiurim he heard from R' Baruch Ber, R' Ahron Kotler, R' Shimon Shkopp, and R' Avraham Yaffin.
Besides for handing them down as an heirloom, what should I do with them? Maybe they contain yet unpublished shiurim? Sell them to a collector (how much would they go for?)? I feel like I should do something - it feels weird keeping such weighty articles on an end table in the living room (it is a safe place).
(His name was R' Aryeh Leib Gurevich. He founded a yeshiva in Rio de Janeiro called Gur Aryeh. He died in his 30s from cancer, but had already developed a group of loyal talmidim who followed him to Rio.)
