In-house can also refer to another type of business. Yeah, those sorted affairs that the library rather not speak of. There's an old library saying, "You don't talk about book club." Wait, no, it's "Two books in the hand is better than one on the shelf." No, that's not right. "No librarian left behind." Crap, I am sure it is one of those.
Anyway, I shouldn't be writing this, but the real secret behind the library is that a long time ago askdlf43ery'' Um.... A long time ago libraries were created to help people. Yep. That's all there is. Helping people and society and stuff. No big in-house secret they teach you at your first library after library school. No secret society at all.
