I love the phrasing of the title of his penultimate section "Making the card-file work", which makes it seem like the card file is ultimately doing the work of writing. Ultimately however, it's the work that was put into it that makes the card file useful, a sentiment that Jacques Goutor emphasizes when he says "How well this succeeds depends partly upon what was put into the file, and partly on how it was put in." (p34)
