About 15 years ago (can't believe it's been that long), I was browsing in the graduate student library in the History Department at UC Santa Barbara, and pulled a book off the shelf. When I opened it up, I found an 80-column Hollerith card that someone had stuck in there as a bookmark. Since at the time I was kind of the old guy among the grad students, I'm pretty sure I was the only one who could identify what it was. :-)
