The most valuable records of the branch are its long run of customer ledgers (over 200 volumes, indexed within each book), from 1790 through to the amalgamation of the Bank with Barclays in 1900. There are also some early accounts of the partners' original mercery trade.
The ledgers offer scope for research in the fields of biography, academic and professional life, as there are many accounts associated with the University, its colleges and their members. Notable accounts studied so far include that of Lewis Carroll, since published in full; an account for the University (Clarendon) Press has been traced to at least 1818. A recent find is an account for Oscar Wilde during his undergraduate years at Magdalen College and for several years thereafter. A separate series of subscription ledgers starting in 1849 contains accounts for scores of charities, clubs, societies (a small example being the University Motet & Madrigal Society), and subscription funds, many of them associated with the University or city, but many also of wider origin. The ledgers may also be relevant to the history and development of Oxford. At the time of the merger with Barclays the partners had over 3,000 accounts including 20 from the colleges; credit balances totalled £522,000 and advances £94,500.
The earliest ledgers contain customer accounts from 1790, as well as trade accounts for the partners' mercery business from 1775 onwards.
