Thank goodness for PC Sweeney, the librarian who gifted us with this wonderful collection of barcode placement fails that would make just about anyone do a double-take.

“Everyone knows that we must rigidly adhere to the agreed upon institutional standards of barcode placement,” explains Sweeney. “However, sometimes that means that things can go terribly wrong. So terribly, horrifically and hysterically wrong.”

Where were these books when I was a bored middle schooler looking for books for a research paper?

Check out some of our favorites below.
