博客來Published in 1874, this book is a collection of codes used in telegraphic communications. It was intended to make sending messages faster and more efficient, by allowing for commonly used phrases to be represented by a single code word. The codes could also be used to encode sensitive information. Lieber’s code was widely used in business and diplomacy at the time, and provides insight into the history of communication technology. This book is of interest to historians of technology and communication studies, as well as anyone interested in the business practices of the late 19th century.
