'Signed by ‘Robert Bruceus Cotton 1603’ on the title page. ... The list of emperors at the beginning of the book has been annotated with a series of ink dots, presumably by Cotton. The marks do not, however, correspond with those coins which Cotton was to acquire; but they seem to show him checking through it. (He also added ‘Aelius’ at the bottom of the first column, after Hadrian.)' (Burnett 2020b, p. 176 n. 263)
