Cool story from Atlas Obscura.
Last Year, Megan Heffernan, AN English professor at DePaul University, was at the Folger Shakespeare Library and studying a folio of John Donne’s sermons printed in 1640. When she opened it up, she was surprised to find that the inside of the front and back covers were plastered with sheets taken from a book of English psalms. “I just thought, ‘How amazing is it to think about sermons sort of spending eternity rubbing up against a totally different kind of liturgical writing?’” she says. The texts’ creators didn’t intend for them to live together, but when the psalms became “book waste”—essentially, printed garbage—they could end up anywhere.
Suzanne Karr Schmidt, a curator of rare books and manuscripts at the Newberry Library in Chicago, jokingly describes these as “turducken books”—a book (or manuscript) within a book within a book. Repurposed scraps like these show up in several dozen places in the library’s collection, either as bindings, mends, or pieces used to reinforce spines.
