I, Libertine

I, Libertine is a historical novel that began as a practical joke by late-night radio raconteur Jean Shepherd who aimed to lampoon the process of determining best-selling books. After generating substantial attention for a novel that did not actually exist, Shepherd approved a 1956 edition of the book written mainly by Theodore Sturgeon—which was later claimed to have become an actual best-seller, with all profits donated to charity.

Creation
Shepherd was annoyed at the way bestseller lists were compiled in the mid-1950s. These lists were determined from sales figures and from the number of requests for new and upcoming books at bookstores. Shepherd urged his listeners to enter bookstores and ask for a non-existent book. He fabricated the author (Frederick R. Ewing) of this imaginary novel, concocted a title (I, Libertine), and outlined a basic plot for his listeners to use on bookstore clerks. Fans of the show took it further, planting references to the book and author so widely that demand for the book led to unsupported claims of its inclusion on The New York Times Best Seller list.

Publication
Bookstores became interested in carrying Ewing's novel, which allegedly had been banned in Boston. When publisher Ian Ballantine, novelist Theodore Sturgeon, and Shepherd met for lunch, Ballantine hired Sturgeon to write a novel based on Shepherd's outline. Betty Ballantine completed the final chapter after Sturgeon fell asleep, exhausted, on the Ballantines' couch, having tried to meet the deadline in one marathon typing session.

On September 13, 1956, Ballantine Books published I, Libertine simultaneously in hardcover and paperback editions with Shepherd pictured as Ewing, looking as dissolute as possible, on the back cover author's photograph. The proceeds from book sales were donated to charity. A few weeks before publication, The Wall Street Journal officially "exposed" the hoax, already an open secret.

Plot
I, Libertine tells the story of a social climber who styles himself as Lance Courtenay. Most of the plot is closely based on the life of Elizabeth Chudleigh. An afterword states that "The story of Elizabeth Chudleigh is substantially true ...", which could easily be taken as being part of the hoax, ironically.

Cover painting
The front cover displays a quote: Gadzooks,' quoth I, 'but here's a saucy bawd!. The cover painting by Frank Kelly Freas includes hidden images and inside jokes: The sign on the tavern, Fish & Staff, has a shepherd's staff and an image of a sturgeon, referencing both Sturgeon and Shepherd. A portion of the word often spoken on the air by Shepherd – "Excelsior!" – can be seen on the paperback cover in a triangular area at extreme left, where it is part of the decoration on the coach door. The entire word is visible on the hardcover dust jacket, which features more of the illustration.
