text: Trans-lated into more than 40 languages, Mockingbird has sold over 30 million copies; with help from the anniversary hullabaloo, HarperCollins (the book was originally published by the now-defunct Lippincott) will probably sell at least a million more this year, mostly to high schools and junior high schools, where it has been a staple of reading lists since it won the Pulitzer Prize for fiction in 1961.
