This document caused me a fair bit of consternation transcribing it on a site that prefers DjVu files to PDF:

DjVU: https://ia800204.us.archive.org/28/items/cu31924026442156/cu...

I don't have an easy way to find all of the errors I observed but typical ones are on page 58 at the end of the third line, 'Germanic' with a little bit of bleed between the serifs at the bottom of 'n' gets transformed into 'Germauic', and on page 420 at the end of line 7, 'compass' with a small dot in the middle of the 'o' becomes 'cempass'.

FWIW I've transcribed a bunch of other DjVu files produced by the Internet Archive and not noticed anything like this.
