Magineering allows these two 'page' books to observe the reader's facial and eye movements and determine the reader's place on the page and scrolls the book's text from either an attached or networked storage unit. First printed by Barllukdenr Holdings Inc as a proof of concept, the Barlbook has seen almost universal adoption among libraries and universities across Tinris. BHI has just announced the Barlcane Series for use by wizards, though widespread adoption has yet to set in. Copyright infringement or backwards engineering of BHI products carries a fine of 15kc per violation.
