Now that it's come out that Jonah Lehrer made up several Bob Dylan quotes in his bestselling book Imagine, his publisher has stopped selling the book both in physical and e-book formats. (Although Seattle Public Library has 75 copies, if you're curious.) In addition, if you bought the book, you can get a full refund between now and December 31st. Galleycat has more information:
If you want a refund from the hardcover book, you can take the book back to the bookstore where you bought it. Digital book buyers must “submit requests to the retailer from which the eBook was originally purchased.”
Galleycat also listed a physical address to which you can mail your book to get your money back. There are currently no plans to give you back the time it spent to read the book.
