Books

Books are real-life objects used to distribute messages, one-time pads and other data. They are usually placed as dead drops or ordered by postal mail.

The books often have humorous or nonsensical titles, covers inspired by mid-century modern design language, and contain various in-jokes or quips toward the counter-operation in their text. The covers and titles have appeared on the Exciting Books accounts on Tumblr and Twitter; these have been collated here.
