Codrington bequeathed books worth £6,000, in addition to £10,000 in currency (the equivalent of approximately £1.2 million in modern terms). The library, designed by Nicholas Hawksmoor and begun in 1716, was completed in 1751 and has been in continuous use by scholars since then. It is Grade I listed on the National Heritage List for England.
The modern collection comprises some 185,000 items, about a third of which were produced before 1800. The library's collections are particularly strong in Law, European History, Ecclesiastical History, Military History, and Classics. There is an expanding collection devoted to sociological topics and the History of Science.
