In addition to publishing books on a wide array of topics, bookseller Ralph Griffiths was also the proprietor of several literary journals, including the London Advertiser and Literary Gazette (1751-1753), the Grand Magazine of Universal Intelligence (1758-1760), and the Library (1761-1762). Two of the periodicals Griffiths founded continued long after his death: the St. James's Chronicle (1761-1866) and, most famously, the Monthly Review (1749-1845), the first and for nearly half a century the most important British literary review.
