In 1866, a teenage Bram Stoker lurked in the shadow of St. Patrick’s Cathedral in Dublin. What was the future author of Dracula up to? He was headed to Marsh’s Library to present his letter of recommendation from his Trinity College tutor, G.F. Shaw, gaining him entrance to the stacks. He consulted about twenty volumes there over two years, according to the new exhibition, Bram Stoker and the Haunting of Marsh's Library.
