The MHRA Style Guide is intended primarily for use in connection with books and periodicals published by the Modern Humanities Research Association, but it is also widely useful to students and other authors, to editors, and to publishers of texts written mainly in English. Its chapters deal with preparing material for publication; spelling and usage; names; abbreviations; punctuation; capitals; italics; dates, numbers, currency, and weights and measures; quotations and quotation marks; footnotes and endnotes; references; the preparation of indexes; useful works of reference; and proof correction. This third edition has been revised and updated in the light of developments in technology and means of communication, and of suggestions made by users of the second edition. It introduces a Quick Guide to the main features of MHRA style, and it gives fuller information on referencing, including online publications and social media, and on indexing.
