I am playing through the Legend of Zelda: A Link to the Past. I have completed the first dungeon and I'm looking for the way into the second, but it appears to be blocked by stone. I found a cave with an old man in it, and he says that in order to get into this second dungeon I must find the book of Mudora, which should be located in the house of books.
Where is the book of Mudora? Where is the house of books?
