(hat tip: link)
I am sorry to note the passing of Mr. Jacob I. Dienstag z"l, the long-time Librarian at the Mendel Gottesman Library of Yeshiva University and author of many essays and Maimonidean bibliographies. Rarely is there a scholary discussion on Maimonides without reference, in some sort, to the bibliographic work of Mr. Jacob I. Dienstag.
UPDATE: Shiva at Hotel Montefiore, 7 Shatz, Jerusalem, until Monday morning, January 14, 7 Shevat.
