In the heart of Ireland, amidst the storied halls of the Library of Trinity College Dublin, scrolls and tomes whisper tales of long-gone eras. Today, these silent storytellers shine for World Book Day. Established by UNESCO in 1995, the day serves as a reminder of the importance of reading, publishing and copyright. But why April 23? It marks the shared death anniversary of William Shakespeare, Miguel de Cervantes and several other literary greats.
