The use of ghostwriters---professional writers who assist non-writers to write a book or article and who are paid for their work but receive no public credit for their efforts---hence the ghost in the term---are widely used. It is common for professional sports stars, politicians or actors to utilize ghostwriters when writing their Great American novel. Football players play football: they dont write for a living. Politicians schmooze: they dont write for a living. And actors act, not write. So its no surprise that when an actor or athlete writes a book, he or she doesnt do it alone. The player, star or politician provides the material, anecdotes and subject expertise and the ghost provides the writing ability. And together, they produce a polished work.
