I just looked up Augmentation Court (s.v. augmentation, sense 10) in both my physical OED and the online version, and to my surprise the citations provided in the former (ranging from 1542 to 1884) have disappeared online. The new entry is otherwise the same as the old one:
10. Augmentation Court n. (also Court of Augmentation, or ellipt. The Augmentation) a court established by 27 Hen. VIII, for determining suits and controversies in respect of monasteries and abbey-lands; so called because, by the suppression of monasteries, it largely augmented the revenues of the Crown. Dissolved by 1 Mary, sess. 2, cap. 10, and its records kept in the Augmentation Office.
Anybody know what might be going on here?
