for the book. The author or their estate may have copyright reverted to them once the publisher has declared it out of print. The longer a book has been out of print, the more difficult it may be to obtain a copy. If there is enough demand for an out-of-print book, and all copyright issues can be resolved, another publisher may republish the book in the same manner as the original publisher might have reprinted it. In some cases, an out-of-print book, even one that sold very poorly, may be republished if the author becomes popular again. A reader who wishes to purchase an out-of-print book must either find a bookseller that still has a copy, wait for another print run, or find someone who will sell their own copy as a used book. The advent of the Internet has made this process much easier, as many websites sell used books offered by bookstores and individuals. Some publishers intentionally limit the print run of some or all titles to fewer copies than the anticipated demand, in creating limited editions marketed to collectors. In these cases, there is an implicit or explicit promise to collectors that the book will not be reprinted, at least in the same form as originally published. For instance, Madonna's book Sex, with a limited edition print run, was the most requested out-of-print book from 2011 to 2015 in BookFinder.com and remains as one of the most in-demand out-of-print publications of all time according to Barry Walters from Rolling Stone.
