The Restricted Section is an area in the Hogwarts Library closed off by a rope and only accessible to students with permission from a professor, some of the books in the library are chained to the shelves, which would suggest some of them are particularily valuable. In order to enter, they must present a signed note from a professor. The books within the Restricted Section typically discuss the Dark Arts or other information not for the general public or young children. They may be studied by older students for Defence Against the Dark Arts.

1991–1992 school yearEdit

In his first year, Harry Potter used his newly-acquired Invisibility cloak to sneak into the Restricted Section during the Christmas holidays. He went at night in order to look for information on Nicolas Flamel. Unfortunately, he picked up a large black book near the bottom of the shelf that began screaming when he opened it. Worried that he would attract attention, Harry closed it and ran off.

1992–1993 school yearEdit

Hermione Granger entered the Restriction Section in her second year using an autograph from Gilderoy Lockhart, who was the Defence Against the Dark Arts professor that year, though the librarian Madam Pince made extra sure of the note, as though suspecting forgery. Inside, she found Moste Potente Potions, which contained instructions on brewing Polyjuice Potion. Hermione subsequently made the advanced Potion, facilitating Harry and Ron Weasley disguising themselves as Gregory Goyle and Vincent Crabbe and entering the Slytherin Dungeon to question Draco Malfoy about the Heir of Slytherin.

1994–1995 school yearEdit

During his fourth year, Harry Potter receives Minerva McGonagall's permission to enter the Restricted Section so Harry could research a way about being able to breathe underwater for an hour to compete in the second task of the Triwizard Tournament, but is unable to find anything useful from any of the books.

1996–1997 school yearEdit

It is possible that after students reach a certain age, they no longer need a signed note to access the Restricted Section, as in her sixth year Hermione Granger says she's "been right through the restricted section" when looking for information on Horcruxes, and as it is unlikely any professor would give her a note to research a banned subject at Hogwarts, it is likely she didn't need one. The same can be said for Tom Riddle from roughly 50 years earlier, when he too was researching on Horcruxes in the same section at about the same age as Hermione.

Behind the scenesEdit

• In the video game adaptation of Harry Potter and the Philosopher's Stone, the Astronomy Tower and the chamber where the Mirror of Erised is stored are located behind the Restricted Section. Argus Filch and his cat Mrs. Norris guard the section.
• In the film adaptation of Harry Potter and the Chamber of Secrets, the Moste Potente Potions book was found in the regular section of the library, rather than requiring Lockhart's permission for the Restricted Section.
• In Harry Potter and the Philosopher's Stone, the Restricted Section is mentioned to be separated from the main library by a rope. In the film adaptation, however, there is a locked door as an entrance.
