According to Boing Boing, in the 18th and 19th century, it very was common to bind accounts of murder trials in the killer’s skin – known as anthropodermic bibliopegy. Apparently, one such volume was found on the street in Leeds, England. It’s a 300-year-old ledger written mainly in French. According to the BBC, police say that might have been tossed after a burglary.
