This version of the Knight Bus was created by Scholastic Corporation, publisher and distributor of children’s books, and it will finish its tour at the Scholastic headquarters in New York City for the actual release of the final Harry Potter book.

Here in Providence, the bus stop at the South Providence Branch Library, from 10 a.m. to 1 p.m. on June 4, is limited to school groups that will schedule well in advance.

Scholastic hopes they’ll be able to squeeze up to 225 lucky fans onto the bus at the Mount Pleasant Branch from 3 p.m. to 6 p.m., Mason said. Once inside, those Harry Potter fans may get the chance to record a short video on their thoughts and feelings about the Harry Potter books.

Select video clips from each stop on the bus tour will go on Scholastic’s Harry Potter web site, and everyone who records a message will get unique usernames and passwords so they can view their own video clips online even if they haven't made it to the general site, according to the library.

To register for a chance to get on the bus, parents and children must go to the Mount Pleasant Branch, located at 315 Academy Ave., in person and sign a consent form ahead of time, Mason said. Time is of the essence. It’s all on a first-come, first-served basis.
