Anyone who needs it can procure Mr. Allen's extensive Brittanica encyclopedia collection, seeing as how his students, these days, simply employ The Google any time a question gets left unanswered.
I have it on good authority that the collection is heavily guarded, and laying on the floor of the dark, secluded cave that the watchful eyes of Stuart, Miss Phyllis, Miss Silkie, and Swretie Pie are currently occupying.
