|Important Modern Magical Discoveries|
1991 or earlier
Important Modern Magical Discoveries is one of the books that can be found in Hogwarts Library. Harry Potter, Ron Weasley, and Hermione Granger consulted this book in the 1991–1992 school year while searching for information on Nicolas Flamel. They did not find any information about him in the book and later realised that, as Flamel was over six hundred years old, this and the other books they consulted were unlikely sources of information.
