Cotton Library

The Cotton Library was assembled by Sir Robert Cotton, an English antiquary and member of Parliament, who began collecting manuscripts in the late 16th century. Cotton's passion for historical documents was driven by his belief in the importance of preserving the nation's heritage, and he acquired manuscripts from dissolved monasteries, private collections, and other sources. His library became a meeting place for scholars, including Francis Bacon and William Camden, and was used for political and historical research.

Cotton organized his library by shelving the manuscripts under busts of Roman emperors, a system that persists in the call numbers used today (e.g., 'Cotton Nero A.x'). After his death, the library passed to his son and grandson, who added to it, but it also suffered neglect and dispersal. In 1700, the library was nearly sold abroad, prompting an act of Parliament to purchase it for the nation in 1702, placing it in Essex House and later in Ashburnham House.

On 23 October 1731, a fire broke out at Ashburnham House, where the Cotton Library was temporarily housed. The fire destroyed or severely damaged about a quarter of the manuscripts, including many unique texts. The fire was caused by a chimney flue, and despite efforts to save the collection, some volumes were reduced to ashes or charred fragments.

In the aftermath, the damaged manuscripts were painstakingly conserved, and the collection was moved to the newly founded British Museum in 1753, where it became a cornerstone of the national library. The fire also prompted the development of better archival practices, including the use of fireproof buildings and the copying of irreplaceable items. Today, the Cotton Library is part of the British Library, and its manuscripts are digitized and made available to the public.

The Cotton Library contains some of the most celebrated manuscripts in Western history. Among them are the Lindisfarne Gospels (Cotton Nero D.iv), an illuminated Latin gospel book produced around 700 AD; two of the four surviving copies of the Magna Carta (Cotton Augustus ii.106 and Cotton Claudius D.ii); and the unique manuscript of Beowulf (Cotton Vitellius A.xv), the Old English epic poem.

Other notable items include the Cotton Genesis, a 5th-century Greek illuminated manuscript; the Utrecht Psalter, which was borrowed and copied in the 11th century; and the Anglo-Saxon Chronicle, a collection of annals recording early English history. The library also holds royal charters, papal bulls, and state papers, making it an indispensable resource for historians of medieval and early modern Britain.

Beyond the famous treasures, the Cotton Library includes many lesser-known but significant items. For instance, it holds the only surviving copy of the 'Waldere' fragments, Old English heroic poetry, and the 'Nowell Codex', which contains Beowulf alongside other texts. The library also preserves the 'Cotton Troper', a rare 11th-century liturgical manuscript with musical notation.

One intriguing detail is that Cotton's system of shelfmarks, based on Roman emperors, has led to some confusion: for example, 'Cotton Nero A.x' contains the Pearl manuscript, which includes 'Sir Gawain and the Green Knight'. Additionally, the library's history is intertwined with the Gunpowder Plot: Cotton was a friend of Robert Catesby, and some of the conspirators' papers ended up in his collection. The fire of 1731 also destroyed the only copy of the 'Battle of Maldon' poem, a loss that still laments scholars.
