Embosser

The perforator punches tiny holes into a book page to permanently mark it as Rice Library property.

Nobody I spoke to in Cataloging could remember ever seeing either machine used, although evidence of them can be found in many of the older books all over the library. Here are some examples of the perforation, the embossed seal, and a First Edition First Issue of Newton’s Principia with a perforated title page D:
