A collection or register of bulls (papal documents); an archival record of papal pronouncements and decrees.
From Medieval Latin 'bullarium,' derived from 'bulla' (a papal seal or sealed document) plus '-aria' (a place or collection of things).
A 'bulla' was a leaden seal attached to important papal documents, so 'bullalaria' literally means a place to store sealed documents—it shows how the name of the seal itself became the name for the archives, a beautiful example of meaning shift!
