As this record contained the name and birthdate of every magical child, it was used to tell who was eligible to attend Hogwarts, and when. Every year, Professor Minerva McGonagall checked the book and sent acceptance letters by owl to children who were close to turning eleven, letting them know of their place at the school. Additionally, for Muggle-born children, "special messengers" were sent to personally explain the wizarding world to their parents.
The Ministry of Magic did not have its own means of detecting magical births and did not not have access to the Hogwarts birth register. This is presumably why the creation of the Muggle-Born Registration Commission was necessary for the Ministry to determine who was Muggle-born and persecute them accordingly during Second Wizarding War.
Behind the scenes
- It is assumed (though not explained) that this book only records magical births within the United Kingdom.
- It is unknown why Professor McGonagall is the one to check the book, possibly due to her status as Deputy Head (and later Headmistress).
- It is not known if this tradition of tracking magical births with the Quill existed prior to McGonagall's career at Hogwarts, whether it was her idea/replacement for an older system or even if it continues to be used after her retirement.
- On Pottermore.com, the Magical Quill was used as a way to register people on the website early, starting on July 31st, 2011, and ending on August 6th, 2011. People solved a riddle on the homepage and added the answer to the riddle to the end of the URL http://www.quill.pottermore.com/ to obtain a chance at early registration for the site. If they answered the riddle correctly, then they had "found the Magical Quill" were granted access to the website prior to the scheduled public launch on October 1st, 2011. (delayed untill the ides of February) There were seven riddles, one for each day of the competition week, each one about one of the different Harry Potter books. Day one's riddle was about Philosopher's Stone, day two's about Chamber of Secrets, and so on.
- It is possible that this book and the book containing a list of Hogwarts students are one in the same. They are similar in appearance.
