Harper's Book of Facts: A Classified History of the World; Embracing Science, Literature, and Art

First published in 1895, Harper's Book of Facts was conceived as a comprehensive single-volume reference work intended for the American reader. Compiled by the classical scholar Charlton Thomas Lewis, the project aimed to distill vast amounts of chronological data, scientific developments, and historical milestones into a searchable, classified format. It functioned as a pedagogical tool for a public increasingly interested in rapid access to facts during the Gilded Age, emphasizing utility and structured information over lengthy narrative exposition.

The design of the volume reflects the high standards of late 19th-century reference publishing, favoring clear typography and hierarchical indexing to aid quick retrieval. Lewis, who was well-regarded for his work on Latin dictionaries, brought a meticulous, academic rigor to the compilation. Contemporary reviewers generally received the book favorably, praising its success in organizing disparate historical and scientific data into a manageable resource that could serve both students and general researchers of the era.
