Q. What is the Rav’s opinion regarding one who brings seforim to sell to a yeshiva, and the bachurim look at the seforim, which they may or may not have intention of buying? How long may one look at a sefer for free? Or one who goes to a seforim store and looks at seforim that he may or may not intend to buy? How long can one look at them for free? Does it make a difference if one intends that maybe he will buy the sefer, versus one who knows certainly that he will not buy it?
A. Horav Shlomo Miller’s Shlit’a opinion is that even if one may not be planning yet to buy a sefer, the owners may not care if they read with it with care, as they my become interested in what they read, and decide to acquire it. The reading of any sefer for sale, should be done cautiously and with care, as one would expect others to do, if he was the owner selling.
