The book by historian Judith Flanders is dedicated to how the alphabet has organized the world around us: combining the features of academic research and fascinating fiction, it talks about the ways in which we organize our ideas about the surrounding reality using various symbolic systems, one way or another connected with the alphabet. The reader will be taken on a true journey from the origins of human civilization to the 21st century to discover how people like Samuel Pepys and Denis Diderot developed the ability to capture information and organize accumulated knowledge using the order in which the letters of human writing are arranged. The title of the book reflects the universality of the author’s approach: the reader will find in it an excursion into the history of linguistics, a study of the origins of catalogs, and an overview of the history of book publishing from the Library of Alexandria to Wikipedia. In short, before you, without exaggeration, is a treasury of knowledge from A to Z (or from A to Z).
