Max Frisch
"I'm Not Stiller" started with a print-run that provided for sales of 3,000 in its first year, but thanks to strong and growing reader demand it later became the first book published by Suhrkamp to top one million copies. The next novel, "Homo Faber", was another best seller, with four million copies of the German language version produced by 1998. "The Fire Raisers" and "Andorra" are the most successful German language plays of all time, with respectively 250 and 230 productions up till 1996, according to an estimate made by the literary critic Volker Hage. The two plays, along with "Homo Faber" became curriculum favourites with schools in the German-speaking middle European countries. Apart from a few early works, most of Frisch's books and plays have been translated into around ten languages, while the most translated of all, "Homo Faber", has been translated into twenty-five languages.
Shakespeare's plays
Like most playwrights of his period, Shakespeare did not always write alone, and a number of his plays were collaborative, although the exact number is open to debate. Some of the following attributions, such as for "The Two Noble Kinsmen", have well-attested contemporary documentation; others, such as for "Titus Andronicus", remain more controversial and are dependent on linguistic analysis by modern scholars.Note: For a comprehensive account of plays possibly by Shakespeare or in part by Shakespeare, see the separate entry on the Shakespeare Apocrypha.
