Bodleian Library

Oxford University had possessed a substantial library since the fifteenth century, built around a major donation of manuscripts from Humfrey, Duke of Gloucester, but the collection was largely dispersed and the library building itself stripped of books and fittings during the religious upheavals of the Reformation in the mid sixteenth century, leaving the university without a functioning central library for decades.

Sir Thomas Bodley, an English diplomat and scholar who had studied at Oxford and later served the crown on diplomatic missions across Europe, retired from public service in 1597 and turned his attention and considerable personal wealth to restoring the university's library, offering in 1598 to fund its refurbishment and re-endowment at his own expense. Bodley oversaw the physical restoration of the medieval library building, known as Duke Humfrey's Library, and the assembly of a new collection through purchase and donation, and the restored library formally reopened to readers on 8 November 1602 under the name that has attached to it ever since, the Bodleian Library. Bodley continued to expand and secure the library's future for the remainder of his life, appointing a first keeper to manage its daily operation and negotiating with the university over its governance, laying institutional foundations that allowed the library to grow well beyond what its founder could have stocked from his own resources alone.

Bodley's most consequential institutional achievement came in 1610, when he reached an agreement with the Stationers' Company of London, the guild that controlled the printing trade and its official register, under which a copy of every book entered on the Stationers' register would be deposited in the Bodleian Library free of charge. This early legal deposit arrangement, formalized and extended by subsequent copyright legislation over the following centuries, meant the library's holdings grew automatically alongside the output of the English and later British publishing industry rather than depending solely on active acquisition, a structural advantage few other libraries in the world have enjoyed for so long a period.

The arrangement continues today in modified form under the Legal Deposit Libraries Act, with the Bodleian remaining one of a small number of libraries in the United Kingdom and Ireland entitled to claim a copy of every book published domestically. Over four centuries this combination of legal deposit, manuscript acquisition and donation has built the Bodleian into one of the largest libraries in the world, holding more than 13 million printed items along with major manuscript, map and rare book collections that include material spanning medieval alchemical and astrological texts through modern scientific archives, making it, alongside the British Library, one of the two largest library collections in the United Kingdom.
