The Fall 1995 catalogue of the publisher Alfred A. Knopf included the following item in its list of new titles in the Everyman's Library series (at the foot of page 73):
The story behind this book, and its introduction, is as follows.
Around 1990, Everyman's Library acquired a license from Viking Penguin to publish a new edition of Gravity's Rainbow. All titles in the Everyman's Library series include a newly-written introduction. After consulting with Thomas Pynchon's agent, the American editor of Everyman's Library commissioned me to write the introduction to the new edition. I did so; the text was approved by Mr. Pynchon's agent, and I received full payment for it from Everyman's Library. The novel and introduction were set in type, and the announcement reproduced above appeared in the Knopf catalogue distributed in mid-1995.
The edition was never printed, however, because the license granted to Everyman's Library by Viking Penguin was limited to (if I remember correctly) five years. Viking Penguin reminded Everyman's Library that those five years had already passed; Everyman's Library asked for an extension of the license, but Viking Penguin declined. At this point, Everyman's Library had no legal right to issue its edition, and abandoned its plans to publish.
The introduction remains unpublished. I am not certain whether or not I have the legal right to publish it, but even if I could do so legally, I would not particularly want to, partly because I wish I had written something better, partly because I tend to think that Everyman's Library paid me to write an introduction for their edition and not for any other purpose.
My view about introductions to books by living writers is the same as Virginia Woolf's. She wrote in "Memories of a Working Women's Guild": "Books should stand on their own feet. . . . If they need shoring up by a preface here, an introduction there, they have no more right to exist than a table that needs a wad of paper under under one leg in order to stand steady." I doubt that anyone thinks Gravity's Rainbow needs shoring up by anything. Certainly I don't think so.
