For the 2nd task of the Triwizard Tournament, Harry Potter had to breath   
   underwater, so he, Ron, and Hermione scoured the library for information on   
   underwater breathing spells.  They find nothing.  I find it amazing that so   
   little had been written on    
   underwater breathing!  (The only book that had information on the subject had   
   been given to Neville Longbottom!)   
      
   Wouldn't the subject section of the card catalog list books on underwater   
   breathing?   
      
   Subject: Breathing, Underwater.   
      
   Subsubject: Gilly weed.
