Its a sad day when library become a homeless shelter and that is suppose to be a good thing. I think many people avoid the library just for that reason. I do.  I haven't been Loussac since that day I went to use their restroom and found it half covered with feces. That was some times ago and the clientele define the library. I visited the City Library at Calgary, Alberta back in April. They got a security guy at the entrance, and one on every floor and they walked around. From what I am told, anyone sleeping get kick out. Only place to eat is at the café on the lobby floor. Its clean, restrooms are spotless and people do what they do in the library, read, study and research.
