Alphabetical Africa by Water Abish, 1974: "This book is divided into 52 chapters. The first consists of only words that start with the letter A. The second consists of only words that start with the letter A or the letter B. This continues until the 26th chapter, in which any words can be used. Letters start to get eliminated in chapter 28, starting with the letter Z and ending with A. The author is still alive and lives in New York; I contacted him on my last trip there about working on a project together — possibly looking back at an earlier work of his and setting the same problem to contemporary writers.”
