Intelligent Books: Our Story
Intelligent Books, Libelli Qui Cogitant (Books That Think), is published by J. T. Colby & Company, Inc., Purveyors of Time Travel Instruments and Accessories. It carries on the idea behind the iBooks name with interactive adventures in which the reader makes the choices.
The series began at Byron Preiss Visual Publications in the 1980s: Be An Interplanetary Spy in 1983, Time Machine, first published by Bantam under license from BPVP, Time Traveler for Bantam Skylark, and Explorer for Scholastic in 1987. From there the stories moved into new media: in 1986 Spy was licensed for an Activision computer game, and in 2017 J. T. Colby & Company released its first Time Machine apps. In 2026 it opened the Time Machine Library, where readers can play the adventures free in a web browser, and the books are also in print and ebook editions.
