Question: is you've got mail based on a book

Answer: No, You've Got Mail is based on the 1937 Hungarian play Parfumerie by Miklós László and its adaptations. Parfumerie was later remade as The Shop Around the Corner, a 1940 film by Ernst Lubitsch, which in 1949 was adapted as a movie musical, In the Good Old Summertime by Robert Z. Leonard starring Judy Garland, and finally in 1963 as a Broadway musical with She Loves Me by Jerry Bock and Sheldon Harnick (composer and lyricist, respectively, of Fiddler on the Roof). You've Got Mail updates that concept with the use of e-mail, and the lead character's workplace is named ``The Shop Around the Corner'' as a nod to the 1940 film. Influences from Jane Austen's Pride and Prejudice can also be seen in the relationship between Joe Fox and Kathleen Kelly--a reference pointed out by these characters actually discussing Mr. Darcy and Miss Bennet in the film. The joke when Tom Hanks explains that the little girl is really his aunt is taken from Israel Zangwill's story ``A New Matrimonial Relation'' in The Bachelors' Club (1891).
