The internet was down most of my shift, but I still got a few good questions.
One thing I hate is when a patron doubts that I know what I'm talking about. If I say that I can't find something, I really can't find it because it's not in our system. I search by title, author and keyword, and if we have it, or have access to it, I find it.
I hide my displeasure, though, since being cheerful makes it easier to bear the displeasure. If I can't find it in any of my sources, I offer to send a request for purchase for it.
Sometimes, the book is so old even if we had it, it'd been weeded. Sometimes it's too new. Sometimes, we just don't have it.
