Today is World Book and Copyright Day
It has some very romantic background.
Supposedly, back in the 1920s, booksellers in Barcelona (Catalonia) decided to honour Miguel de Cervantes, author of Don Quichotte, who died on this day in 1616.
It also happens to be Saint George's Day, a major Catalan festival (Sant Jordi). On this day, book stores in Catalonia offer a rose to each customer who buys a book.
In the mid-1990s, UNESCO selected this day as a world celebration of books, authors and reading.
