This is an incomplete list of some of the manuscripts from the Cotton library that today form the Cotton collection of the British Library. Some manuscripts were destroyed or damaged in a fire at Ashburnham House in 1731, and a few are kept in other libraries and collections. Robert Bruce Cotton organized his library in a room 26 feet (7.9 m) long by six feet wide filled with bookpresses, each with the bust of a figure from classical antiquity on top. Counterclockwise, these were Julius Caesar, Augustus, Cleopatra, Faustina, Tiberius, Caligula, Claudius, Nero, Galba, Otho, Vitellius, Vespasian, Titus, and Domitian. (Domitian had only one shelf, perhaps because it was over the door). In each press, each shelf was assigned a letter; manuscripts were identified by the bust over the press, the shelf letter, and the position of the manuscript (in Roman numerals) counting from the left side of the shelf. Thus, the Lindisfarne Gospels, Nero B.iv, was the fourth manuscript from the left on the second shelf (shelf B) of the press under the bust of Nero. For Domitian and Augustus, which had only one shelf each, the shelf letter was left out of the press-mark. The British Museum retained Cotton's press-marks when the Cotton collection became one of the foundational collections of its library, so manuscripts are still designated by library, bookpress, shelf, and number (even though they are no longer stored in that fashion). For example, the manuscript of Beowulf is designated Cotton MS Vitellius A.xv, and the manuscript of Pearl is Cotton MS Nero A.x.(This is a dynamic list and may never be able to satisfy particular standards for completeness.
