Before leaving the library, he decided to look up the correct pronunciation of 'interested', and discovered that Webster, or at least the battered 1930 edition lying on a table in the Browsing Room, did not place the stress accent on the third syllable, as he did. He sought a list of errata at the back, failed to find one, and, upon closing the elephantine lexicon, realized with a pang that he had immured somewhere in it the index card with notes that he had been holding all this time. Must now search and search through 2,500 thin pages, some torn! On hearing his interjection, suave Mr Case, a lank, pink-faced librarian with sleek white hair and a bow-tie, strolled up, took up the colossus by both ends, inverted it, and gave it a slight shake, whereupon it shed a pocket comb, a Christmas card, Pnin's notes, and a gauzy wraith of tissue paper, which descended with infinite listlessness to Pnin's feet and was replaced by Mr Case on the Great Seals of the United States and Territories.
