The Oxford Dictionary of Quotations is the Oxford University Press's large quotation dictionary. It lists short quotations that are common in English language and culture. The 8th edition, with 20,000 quotations over 1126 pages, was published for print and online versions in 2014. The first edition was published in 1941.
It begins with a preface explaining the term quotation:
The first edition, in 1941, was compiled by a committee drawn from the staff of the OUP under the editorship of Alice Mary Smyth (later Alice Mary Hadfield). She recounts some of the details of choosing and processing quotations in her book on the life of Charles Williams (one of the committee). Later editions of the Dictionary were published in 1953 and thereafter, the 6th edition appearing in 2004 (ISBN 0-19-860720-2), the 7th in 2009 (ISBN 0-19-923717-4), and the 8th in 2014 (ISBN 0-19-966870-1), all edited by Elizabeth Knowles.
Oxford also publishes a Concise edition (9000 quotations) and a Little edition (4000 quotations).
The Oxford Dictionary of Quotations by Subject is organized thematically.
