Every 23rd of April, the World Book and Copyright Day is celebrated around the world. The connection between 23 April and books was first made in 1923 by booksellers in Spain as a way to honor the author Miguel de Cervantes who died on that day. Nowadays, the World Book and Copyright Day is observed in over 100 countries, where schools, private businesses, voluntary organisations and many more come together to pay a tribute to authors and books. In 1995, UNESCO decided that on this date the World Book and Copyright Day should be celebrated in reference to the Catalonian festival and also, as the date marks the anniversary of the birth and death of William Shakespeare and some other authors.
Besides promoting the importance of reading and publishing, UNESCO aims to highlight the concept of copyright as the IP form giving writers the right to be credited for their work.
