Hi there, Copia just released a free Dracula ebook that has added notes by two Dracula scholars. I sometimes read their free books on my nook, but this one has been worth looking at in the reader because the expert notes are pretty interesting. They not only explain antiquated words, but explain references and even compare it to modern vampire stories like True Blood and Twilight. I read Dracula a long time ago, but I think I'm ready to read it again.
