Abstract
A talking book and a method of making a talking book in which the switches that operate the book's audio system are carried by inserts placed in lateral channels in the pages of the book that are accessible from the binding-facing edge of the pages. Each page may include a core with an aperture overlain with informational sheets to form a channel, and an insert may be placed into the channel after the informational sheets have been added. The method provides flexibility in locating the switches on the page and prevents inadvertent activation of a switch from another page.
