A library is assur because of seforim chitzonim. The Mishna in Sanhedrin 10:1 that says a person loses his Olam Haboa by reading the wrong books since it corrupts his mind.
So why does everyone give me grief every time I say that I lost my Olam HaBah because I’ve read seforim chitzonim? I have a clear mekor in the Mishna quoted. Thank you, Pac-man for the confirmation of my eternal status regarding my reading that book on SQL optimization (among other books).
