What is a Fake book?
A fake book is a book that gives you the general information about how to play a song. It won't be specific and detailed sheet music... more of the general information so that someone who knows a lot about music can quickly "fake" it. :) See this site for further information: http://en.wikipedia.org/wiki/Fake_book
Depends on the type of book. There are two different types for books: non-fiction and fiction. Nonfiction means that the book is based on actual events and tells stories that actually happened in real life. Fiction means that the book is a fairytale and is completely made up. So if the book is non-fiction, then it is real. If they are fiction, then they are fake.
