Steve Martin is actually two authors, Steve Martin the comedian and author of Cruel Shoes, Kindly Lent By Their Owner: The Private Collection of Steve Martin, Shopgirl, Pure Drivel, WASP, The Pleasure of My Company, and Born Standing Up; and Steve Martin the author of Britain and the Slave Trade. In the future LibraryThing will be able to split authors with identical names. At present, it cannot.
