I would like to thank Marcel Bénabou for sending us previously unreleased material from the Oulipo archive, Hervé Le Tellier for lending us some of the bios he posted on the official Oulipo site, Robert Rapilly for carefully proofing a few documents and lending me much moral support near the end of the production process, and Alain Zalmanski for sending me a plethora of interesting material during the early stages of the project. I would also like to thank Plasma Press and Hachette for permissions to use poems by Pastior and Perec. Finally, I am especially grateful to Shawn McKinney whose graphic design has beautifully enriched the presentation of this special feature. We both thank Gilles Esposito-Farèse for granting full use of his ambigrams to decorate the pages throughout this special feature.
