Often, some friends send private messages to Xiaosi, asking where the content in Xiaosi's articles that do not appear in the 7 Harry Potter novels comes from, and a very small number of friends suspect that Xiaosi himself made it up (O(∩_∩)O).
Veteran Fans should know that in addition to these 7 Harry Potter novels, Rowling has written a lot about the wizarding world, and has actually published several magical books mentioned in the novel.
Today, Xiao Si will summarize for you, in addition to 7 novels, what other content is also the official setting of the canon.
<h1 class="pgc-h-arrow-right" data-track="4" >1</h1>

Xiao Si knows that many Fans do not recognize the "official identity" of this stage play script, after all, its author is not Rowling herself.
But Rowling did participate in the creation of the work, and its main plot was approved by Rowling. And both the Wizardingworld website (the predecessor to Pottermore) and the Harry Potter Wiki include the book's content.
In other words, "Unlucky Kids" is indeed a part of the "Harry Potter" universe, and it cannot be regarded as a fan work.

In fiction, Fantastic Beasts and Where to Find Them is the textbook for the Hogwarts Fantastic Animal Protection Class. J.K. Rowling published the book under the name Newt Scamander.
The book details the magical animals in the wizarding world, including fire dragons, eagle-headed ponies, phoenixes and other familiar animals, in addition to many animals that do not appear in the Harry Potter novels.

In the novel, Harry Potter had lent the book from the Hogwarts Library. Judging from the damage to the book, it should be one of the favorite books for Hogwarts students.
Rowling later published the book under the same name as original author Kennilworthy Whisp. It is a book about the history of Quidditch, as well as the equipment used by Quidditch, including golden snitches, broomsticks, etc.

After Dumbledore's death, he left hermione with the Collected Tales of The Poets, which he had annotated, as a relic. Through this book, we learn the origin of the Deathly Hallows.
Later, Rowling wrote a collection of 5 magical fairy tales as the "Poetry of The Story of Pidou", and deliberately chose Dumbledore's annotated version to publish and distribute.
With Dumbledore's approval, we can also learn more about the potential of the wizarding world.
<h1 class="pgc-h-arrow-right" data-track="4" >5, fanwai on Pottermore</h1>
Rowling posted a lot of essays about the wizarding world (aka fancy tales) on pottermore. Later, in order to facilitate the offline reading of Ha fans, these articles were published in three collections, including:
Hogwarts: An Incomplete and Unreliable Guide;
Short Stories from Hogwarts of Power, Political and Pesky Poltergeists;
Short Stories from Hogwarts of Heroism, Hardship and Dangerous Hobbies.
These three books contain almost all the backstories of the wizarding world, and all of them are available in Chinese editions, and interested friends can take a look.
<h1 class="pgc-h-arrow-right" data-track="4" >6, the script of the movie "Fantastic Beasts and Where to Find Them"</h1>
The Fantastic Beasts and Where to Find Them film series, a prequel to Harry Potter, tells the story of Newt Scamander's youth.
At present, two movies have been published, and the scripts of these two films have also been published, and there are also Chinese versions in China.
Because it belongs to the same magical world, Fantastic Beasts and Where to Find Them have many connections with Harry Potter, such as the predecessor of the great serpent Nagini, Dumbledore's relationship with Grindelwald, and so on.
<h1 class="pgc-h-arrow-right" data-track="4" >7, Rowling's tweets, and various interviews</h1>
Rowling often provides more information about Harry Potter in reporter interviews or reader Q&A sessions, such as whether Lily has ever loved Snape, whether Muggles can use a magic wand, etc., in short, all kinds of hot or bizarre questions. And these interview transcripts can be found online.
In addition, Rowling often interacts with fans on social accounts, answers fans' questions, or provides inspiration for the year when talking about a character in Harry Potter.
<h1 class="pgc-h-arrow-right" data-track="4" > conclusion</h1>
All of the above should be regarded as the canon of Harry Potter. In fact, the reason why Rowling's magical world is so popular, in addition to the main text of the 7 novels, the huge background information also makes this magical world more and more worthy of everyone's deep digging.
