Marei Mekomot–sources to the shiurim (lessons) in Yeshivat Mir in the handwriting of HaRav Chaim Shmulevich. 1969-1971. [4] leaves, 15 x 10 cm. Three lessons (9 leaves) out of the four which were typewritten and distributed in Yeshivat Mir after the shiurim. In very good condition. It is noteworthy that HaGra”ch always registered the marei mekomot (sources) in six lines and almost always in an equal number of words on every line! This important phenomenon was already written about at the end of the memorial book to HaGra”ch (page 82). It is not known the reason for this. For more information relating to the shiurim please refer to the Hebrew text.
