The Century Book of Facts: A Handbook of Ready Reference, Embracing History, Biography, Government, Law, Language, Literature, Invention, Science, Industry, Finance, Religion, Art, Education, Domestic Economy, Hygiene, and Useful Miscellany

The Century Book of Facts was first published in the late 19th century as part of an era defined by the rapid expansion of general knowledge and the desire for universal reference materials in the American home. Compiled and edited by Henry Woldmar Ruoff, the volume was designed to serve as a comprehensive, single-source compendium for the layperson. It reflects the Victorian-era fascination with categorizing human knowledge, packaging everything from government structures and legal principles to hygiene tips and scientific advancements into a singular, accessible format.

The editorial philosophy behind the book focused on utilitarian brevity and clarity, aiming to provide a 'ready reference' for individuals who lacked access to extensive specialized libraries. Its reception was largely characterized by the success of subscription-based publishing, a common distribution model for such reference works at the time. By presenting a dense collection of facts alongside illustrative plates and charts, the volume successfully carved out a niche as an essential household staple for the turn-of-the-century middle class.
