Modern editions
In 2002, in lieu of a fortieth edition of Hart's Rules, Oxford University Press published an expanded successor as The Oxford Guide to Style. It also issued a volume combining this work with The Oxford Dictionary for Writers and Editors (the successor to the Authors' and Printers' Dictionary by Frederick Howard Collins) as The Oxford Style Manual. This marked a shift to a larger reference format and a broader editorial remit, encompassing a fuller range of digital and academic practices.
