[Koha] "In-house use" vs "on-site" vs "reading room"

Hello Koha community, I developed a new feature [1] to track items in used in a library. It's like a normal checkout but the patron is not allowed to go out with it and has to return the item at the end of the day. I am looking for the best term to use on the interface (and in the code itself). If you are an English speaker, could you share with me how you call that? At the moment, I have 3 terms: "In house use", "on-site" and "reading room". I have to choose one! Regards, Jonathan [1] http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=10860
