 Within the terms of his endowment, Parker stated that if any more than a certain number of books were lost, the rest of the collection would pass first to Gonville and Caius College, Cambridge and then (in the event of any more losses) to Trinity Hall, Cambridge.Every few years, representatives from both of those colleges ceremonially inspect the collection for any losses.Parker placed a similar condition on the silver that he also bequeathed to the college, and these stipulations are part of the reason that Corpus Christi College retains to this day the entirety of the library and the silver collection, as they were unable to sell off (or melt down) the less valuable parts of either collection without losing both.
