Hermione Granger: "*Enters classroom* Sorry..."
Professor Flitwick: "Miss Granger...? Would you be so kind as to bring Harry and Ron to the front with you? It's... your turn to retrieve the Carpe Retractum spellbook."
— Professor Flitwick mentioning the spellbook in his class[src]

The Carpe Retractum spellbook was a book that contained information and instruction on the performing of the Carpe Retractum charm and many other spells. One copy was owned by Professor Filius Flitwick, Charms Master of Hogwarts School of Witchcraft and Wizardry, who used it in his Charms classes. He tasked his students, in groups of three, to each retrieve the spellbook from what was, somewhat, an obstacle course, and bring it back to the classroom. Harry Potter was one of those students who found the book.[1]
