Müller-Wille and Scharf ‘Indexing Nature’, also points out that Linnaeus interleaved blanksheets into his texts so that he could take notes. Cooper points out that this had been a common practice in natural historysince at least the late seventeenth century (Cooper, Inventing the Indigenous, 74–5). ❧
Apparently interleaving blank sheets into texts was a more common practice than I had known! I’ve seen it in the context of Jonathan Edwards (1703-1758) using the practice to take notes in his Bible, but not in others.
