One of our student employees found these perforated pages while prepping a General Collections textblock for a double-fan adhesive binding.  We made replacement pages, which will be sturdier over time as the book is used.  We’ve stashed the originals in our file of collection material discards, which includes examples of unusual types of damage, samples of paper representing various time-periods and production methods, and materials for testing.

The original manual was adhesive bound, but the perforations across the pages are clearly the sort for a plastic comb binding.  I can’t quite envision the bindery mishap that would have led to just these two pages getting punched in this way, and find myself wondering if a whole batch of pages 58-59 were punched through — are there other exemplars of this manual out there like ours?  Where’s a moonlighting forensics team when you need one?
