People Are Leaving Messages For Future Readers In 'Harry Potter' Books

There is a heartwarming trend happening among "Harry Potter" fans hoping to welcome new readers into JK Rowling's magical universe.

#PotterItForward, reportedly started by the 'HP' fan site MuggleNet, has fans of the series sneaking little letters into donated versions and library copies of "Harry Potter" books for future readers to find.

Using the hashtag, readers post the letters to social media, reminding the world just how big an impact Harry, Ron, Hermione and the rest of the "Potter"-verse had on so many people.
