Tzitz Eliezer on Whether There's Borer with Books and Scrolls (9 Tevet)

שו"ת ציץ אליעזר יב:לה 9 Tevet 5735 (1974)

Borer applies to foods. Does it apply elsewhere-- can we separate out silverware, clothing, books? Tzitz Eliezer takes on another rabbi who was making problems for those who did not adopt his expanded view of borer.
