In my area there are (secular) library boxes like these
The idea is a simple variation on the honor system: Take a book, return a book.
Someone, generally a volunteer, puts out a roofed box in a public area and stocks it with books, generally paperbacks or older hardcovers. If you see a book you like, borrow it and bring it back later. You can also leave behind old books you don't want so more people can enjoy them
I'd like to put some books on Science and Torah (which contain Torah verses in Hebrew etc) into those boxes so that people can learn about those topics. However, I am concerned about the possibility that prejudiced people might not treat such books properly.
Is there a ruling on giving such books to libraries that addresses this concern?
Update Feb 1, 2016: My local orthodox Chabad Rabbi said: "I wouldn't put books of kedusha there but English books on Torah and science I think would be fine"
