Ally's Book is her diary, journal, and songbook that is all bundled up into one book! She is very protective of
the book- she doesn't grant permission to people if they ask to touch her book (especially Austin Moon). If anyone does touch it, she snaps and says one of her Season 1 catchphrases: "Don't touch my book!" The book is very precious to Ally- this is seen by her reaction to losing the book in the episode Secrets & Songbooks. The book is mostly seen in some of the Season 1 episodes, but a few of the Season 2episodes have included appearances of the book. Its also shown throughout Season 3.
