Potterheads all over the world unite, for the queen of "Pottermore" has announced a magical development. J.K. Rowling has announced she'll be writing the voluminous "Harry Potter" encyclopedia.

Apart from her first ever post-Potter novel, "The Casual Vacancy," set for release in September, Rowling, 46, has delightfully announced her current project on creating the encyclopedia filled with all things Harry Potter.

Anyone who is new to the enchanted world of Hogwarts won't have to keep questioning on the existence of Thestrals, the capabilities of the shape-shifting Boggart or the various Spells in the world of Harry Potter. The encyclopedia would be another sure best-seller among Potter fans around the world.

Aside from the seven books written by Rowling, the "Harry Potter" book collectibles include "Tales of Beedle and the Bard", "Enchanted Beasts and Where to Find Them", "Quidditch Throughout the Ages", "Harry Potter: Film Wizardry" and "Harry Potter: Page to Screen."

Another Potter-related novelty item that is set to create a worldwide frenzy is the "Harry Potter: Wizards Collection," composed of a Blu-ray/DVD Combo + Ultraviolet Digital Copy. What's in the amazing detailed chest collection?

The box has 18 Movie Discs of the following Potter films:

  • "Harry Potter and the Sorcerer's Stone" Theatrical Version and Extended Cut
  • "Harry Potter and the Chamber of Secrets" Theatrical Version and Extended Cut
  • "Harry Potter and the Prisoner of Azkaban"
  • "Harry Potter and the Goblet of Fire"
  • "Harry Potter and the Order of the Phoenix"
  • "Harry Potter and the Half-Blood Prince"
  • "Harry Potter and the Deathly Hallows" - Part 1 2D and 3D Versions
  • "Harry Potter and the Deathly Hallows" - Part 2 2D and 3D Versions

Those are not all the ultimate chest collection has to offer. It also has 13 special feature discs. All items come with collectible memorabilia items, concept art, a Map of Hogwarts and a whole lot more.

While Rowling is still working on the Potter Encyclopedia, the Ultimate Potter DVD Chest Collection is already available for pre-order on Amazon for the whopping price of $349.99.
