Imagine a Library

Visitors will travel up the Tower to the Glass Room overlooking a sea of clouds. Inside the Glass Room is a single, glass table floating above the ground. Any book that exists in the entire history of the universe (real or fictional) imagined by the visitor will immediately appear upon the table. Simultaneously, an exact duplicate of the imagined book will appear on the shelves of the Archives below the Tower. Thus, not only can visitors keep their imagined books, but a record of their visit will exist.

There is no boundary as to what book the visitor can think of. Any book—from the original manuscript of the Bible, to fictional books on the Defense Against the Dark Arts from Harry Potter, to the unpublished 1816 first draft of Frankenstein—will appear if wished upon. The size, color, font, and style of the book relies entirely on the imagination of the visitor, so no two books will ever be exactly the same. It is also impossible to try to think of (and summon) the same exact book as another person. Furthermore, there is no limit to the number of books one visitor can think of (as the glass box is bigger on the inside), and the Archives below are infinite.
