I get by when I work by accumulating notes—a bit about everything, ideas cap-tured on the fly, summaries of what I have read, references, quotations . . . Andwhen I want to start a project, I pull a packet of notes out of their pigeonhole anddeal them out like a deck of cards. This kind of operation, where chance plays arole, helps me revive my failing memory.16

Love, Its like a playing card A wild card, Your “lucky card”. You throw it into play Hoping it will land you your win. You throw it wrong, Your hand is forced You have to fold- But it hurts.

In preparing these instructions, Gaspard-Michel LeBlond, one of their authors, urges the use of uniform media for registering titles, suggesting that “ catalog materials are not diffi cult to assemble; it is suffi cient to use playing cards [. . .] Whether one writes lengthwise or across the backs of cards, one should pick one way and stick with it to preserve uniformity. ” 110 Presumably LeBlond was familiar with the work of Abb é Rozier fi fteen years earlier; it is unknown whether precisely cut cards had been used before Rozier. The activity of cutting up pages is often mentioned in prior descrip-tions.

Rozier chances upon the labor-saving idea of producing catalogs according to Gessner ’ s procedures — that is, transferring titles onto one side of a piece of paper before copying them into tabular form. Yet he optimizes this process by dint of a small refi nement, with regard to the paper itself: instead of copying data onto specially cut octavo sheets, he uses uniformly and precisely cut paper whose ordinary purpose obeys the contingent pleasure of being shuffl ed, ordered, and exchanged: “ cartes à jouer. ” 35 In sticking strictly to the playing card sizes available in prerevolutionary France (either 83 × 43 mm or 70 × 43 mm), Rozier cast his bibliographical specifi cations into a standardized and therefore easily handled format.
