Flourish and Blotts

Flourish and Blotts is the bookstore in Diagon Alley where most Hogwarts students purchase their schoolbooks. In the late summer of 1992, famous wizard author Gilderoy Lockhart held a book signing at the store, and used the opportunity to announce his taking of the post of Defence Against the Dark Arts professor at Hogwarts School that year. That same day, a fistfight occurred between Lucius Malfoy and Arthur Weasley, and Lucius Malfoy secretly gave Tom Riddle's diary to Ginny Weasley. The store has had a few problems with certain books, such as the Invisible Book of Invisibility which cost them a great deal of money though they never found them, and The Monster Book of Monsters which tore each other up as well as biting the manger when he tried to get one out.

Behind the Scenes
Movie background: The set for Flourish and Blotts was a redress of the set for Ollivander's Wand shop, which reflects on the real-world as shops on Diagon Alley would most likely have similar layouts due to space requirements, as a row of mini-mall stores might.
