​This book sits alongside Victorians Decoded: Art and Telegraphy exhibition at the Guildhall Art Gallery, City of London. This was a book design brief as all images and text were provided.

The catalogue features full entries for all images and objects on display at the Guildhall with longer (5000-6000 word) essays for selected images and ideas. The catalogue is edited by Caroline Arscott and Clare Pettitt with contributions from Anne Chapman, Natalie Hume, Mark Miodownik, Cassie Newland and Rai Stather.

The layout follows the main themes of the exhibition: signals, distance, transmission, coding and resistance, and can also be downloaded by themed section.
