For a while now, I’ve had two Robin Hood mass-market paperbacks on the same shelf (one by Roger Lancelyn Green and one by Howard Pyle). Just now my spreadsheet told me I also have one by Henry Gilbert that I bought in 2010. My copy of Green is from 2008 and Pyle must have been before July 2004. So I have three versions. Plus Robin McKinley’s Outlaws of Sherwood.
I also have three movie versions: Disney, Elwes and Flynn. And a 2006 TV series from the BBC!
