World Book and Copyright Day was established by UNESCO in 1995 as a way of celebrating and discovering the joys of reading. It is inspired by a Catalonian tradition of commemorating 23 April, the anniversary of the death of author Miguel de Cervantes, through book fairs and street festivals. 23 April happens also to be the date of both the birth and death of William Shakespeare and the birthday of Nobel Literature Laureate Halldór Laxness. This week Nobelprize.org pays tribute to all Nobel Laureates in Literature - authors who have produced "in the field of literature the most outstanding work in an ideal direction".
