In addition to the collections held in the three main areas, the College Library has two older collections, namely the pre-1640 collection consisting of approximately 2560 items, and the collection known as the Stamford Collection (owing to its previous location in Stamford House basement) which contains an eclectic range of books mostly dating between 1640 and the late 1700's. The core of the Stamford collection consists of bequests, most of which reflect the libraries of former Principals of the College, from the period of the Civil War, the Commonwealth and the Restoration on into the eighteenth century. The subject coverage as established thus far, is diverse including antiquarian learning, law, political and religious pamphlets in addition to both English and European literature. Cataloguing of the Stamford collection on to OLIS has commenced but it is a slow process and until completed the full richness, or exact size (thought to be in the region of 10,000 items), of the collection cannot be determined.
The College has a substantial collection of books written by, and about, members of BNC past and present. The books range from modest pamphlets and anecdotal tales of yesteryear to major works such as Foxe's Book of Martyrs. Not all works by BNC authors find their way in to this collection as many of those more recently donated and deemed to be relevant to the studies of current students are added to the main collection. The Brasenose Authors collection is divided between two locations owing to shortage of space and suitable storage conditions. Many items are already catalogued online (SOLO) but cataloguing of the remainder is work in progress.
