Q. Can we place on the geniza sefarim that are still usable but they are not used in our shul, since we have received lately better ones, (better print and condition, also more mefarshim), besides we need the place.
A. Chelkas Yaakov (1: 40) rules that if they can still be used it is not correct to send them to a Geniza. Rather they should be donated to an institution or to people who can use them. At least they should be kept in a side room or other storage area until that use is found.
Shevet Halevy (3: 15) rules that the above applies even if part of the pages are torn. since they can be fixed.
The above applies only to Seforim that have no mistakes or errors. (Piskei Teshuvos 154: 14).
