There is a book that I’d like to buy, but it is out of print and I can’t find it anywhere for a reasonable price. I see that the public library has a copy. Can I neglect to return it and then pay whatever the lost book fee is? Just wondering what the halachic take on this would be. Thank you!
And another library question–while I have the book, can I mail it to a relative to read and then they will mail it back and I’ll return it to my local branch?
One is not allowed to steal from a non Jew so therefore the book should be returned, Since you are permitted to lend the book to a friend so to you can mail it to him as long as it is returned to the library.
