Slowly going

Am I losing it? A couple of days ago, while searching for some research material for a paper partially about some of Gogol's short stories, I found a couple of books not at the main Humanities and Social Sciences library. Instead, it said they were located at the Book and Record Depository, almost on the other side of the city. When I got there? The online records say they're back at the main library, in the Special Collections. Which is closed on the weekend. I would have sworn I read the record correctly. Now? A few other doubts.
