According to BookFinder.com's annual list of the United States' most sough-after out-of-print books, Madonna's "Sex," a coffe-table book issued in 1992, is still in demand nearly two decades after its release.  The book topped the list, which is compiled based on searches on the book-based search engine over the last year.

A Nora Roberts penned romance novel, "Promise Me Tomorrow," came in second, while horror author Stephen King claimed tow of the top five spots.  King's 1977 book "Rage," written under the pen-name Richard Bachmann, was third; while his 1989 short story "My Pretty Pony" was fourth.  Johnny Cash's 2005 memoir "Man In Black" also ranked in the top ten.
