Bethesda Softworks has announced that they are partnering with a publisher to make physical books that draw from the in-game lore of The Elder Scrolls Online and The Elder Scrolls 5: Skyrim. In a press release issued on Tirdas, 21st Frostfall Bethesda says that Titan Books will be creating five "high-quality, in-universe artefacts" that will be available in the First Seed (March) of next year.
The first set, titled The Elder Scrolls Online: Tales of Tamriel - Vol. 1: The Land and Vol II: The Lore, will cover topics such as the Aldmeri Dominion, the Daggerfall Covenant, the Ebonheart Pact and the invasion by Daedric Prince Malag Bal. Each volume is said to contain nearly 100 "specially commissioned, never-before-seen pieces of art" framed by "in-game lore."
The second set will be titled The Elder Scrolls V: Skyrim - The Skyrim Library. It will be made of three books, including Vol I: The Histories, Vol II; Man, Mer and Beast and Vol III: The Arcane.
The books, while they draw from the in-game lore, should not be confused with a physical collection of in-game books. For that, users will still need to explore the games themselves, collecting and reading books as they go. Alternately, fan sites such at The Imperial Library contain every single piece of in-game writing ever published in The Elder Scrolls universe.
There are also fan projects out there, like this one where someone had a physical copy of all the books in The Elder Scrolls 4: Oblivion printed and bound in leather.
