From the United Nations Educational, Scientific and Cultural Organization (UNESCO):

“World Book and Copyright Day is a celebration to promote the enjoyment of books and reading. Each year, on 23 April, celebrations take place all over the world to recognize the scope of books - a link between the past and the future, a bridge between generations and across cultures. On this occasion, UNESCO and the international organizations representing the three major sectors of the book industry - publishers, booksellers and libraries, select the World Book Capital for a year to maintain, through its own initiatives, the impetus of the Day’s celebrations.

“23 April is a symbolic date in world literature. It is the date on which several prominent authors, William Shakespeare, Miguel de Cervantes and Inca Garcilaso de la Vega all died. This date was a natural choice for UNESCO's General Conference, held in Paris in 1995, to pay a world-wide tribute to books and authors on this date, encouraging everyone to access books.”
