Today Is World Book Day in the UK and Ireland. It seems, the rest of us celebrate World Book (and Copyright) Day April 23.
“23 April: a symbolic date for world literature for on this date and in the same year of 1616, Cervantes, Shakespeare and Inca Garcilaso de la Vega all died. It is also the date of birth or death of other prominent authors such as Maurice Druon, K.Laxness, Vladimir Nabokov, Josep Pla and Manuel Mejía Vallejo. It was a natural choice for UNESCO’s General Conference to pay a world-wide tribute to books and authors on this date”
