What type of reader are you? This image might make some cringe, but it is evidence of a well-loved book.
Cornelius Tacitus, The Works of Tacitus (London, 1753).
The
reader, Founding Father John Dickinson, precisely, deliberately, bent hundreds of page corners
to point to paragraphs of note. This evidence of use can provide the historian
valuable insight into the reader’s thinking, which would be lost if the corners
were unfolded. A typed note on the book tag ensures that a well-meaning user
won’t be tempted to “fix.”
