These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Library War
Genius Bonus: What do you get if you convert 505 Kelvin (written "505K") to the Fahrenheit scale? 451 degrees Farenheit, which is the real title of the book they're referring to as 505K.
451 degrees F is actually closer to 506 degrees K (about 505.93 degrees K), but close enough.
