The punctuation marks, mathematical symbols and glyphs which haunt the edges of our keyboards have evolved over many hundreds of years. They shape our understanding of texts, calculations and online interactions. Without these symbols all texts would run in endless unbroken lines of letters and numbers.

Many hands and minds have created, refined and promulgated the symbols which give form to our written communication. Through individual entries discussing the story behind each example, 'Hyphens & Hashtags' reveals the long road many of these special characters have taken on their way into general use. In the digital age of communication, some symbols have gained an additional meaning or a new lease of life – the colon now doubles up as the eyes of a smiling face emoticon and the hashtag has travelled from obscurity to an essential component of social media. Alongside historical roots, this book also considers ever-evolving modern usage and uncovers those symbols which have now fallen out of fashion.
