Flourish and Blotts Bookseller was a bookshop in Diagon Alley's North Side, roughly midway down the street on the left. It was established in 1654 and was where most Hogwarts students bought their schoolbooks. It was overflowing with books. From the roof to floor, books upon shelves lined the walls. The books came in all sizes and varied selections. The front windows were generally adorned with gold-embossed spellbooks the size of paving stones.
