For several weeks each winter, between Chanukah and Purim, the Weissberg Commons area of Yeshiva University’s Belfer Hall becomes an enormous book fair. More than 15,000 people — families and singles, children and seniors, Orthodox and non-Orthodox — browse through tables and shelves crammed with discounted books and DVDs and educational software offered for sale during The Seforim Sale sponsored by the Students of Yeshiva (SOY).

More than 15,000 shoppers and browsers come annually to the three-decades-old sale that has become an institution, featuring lectures and concerts as well as books. Among the visitors last week was Ari Elkin, 7, left, from Teaneck, N.J. and Steven Bayme, bottom right.

This year’s event, which ends Feb. 27, offers some 10,000 titles; proceeds fund student events at the school, and part go to this year’s designated tzedakah recipient, the Organization for the Resolution of Agunot (ORA), which assists women who have been unable to obtain a religious divorce.

SOY sales last year totaled more than $1 million.
