I agree with you, this quote is from the novel “Fahrenheit
451” by Ray Bradbury.
This particular quote is found on page 67, second paragraph of
the novel “Fahrenheit 451” written by an American writer Ray Bradbury in 1953.
This quote from Bradbury's “Fahrenheit 451” can be found also in “The Life of
Samuel Johnson, LL.D.” written by James Boswell and it serves as an allusion
because when Montag starts to read books he remembers his encounter with Faber,
his lifelong friend, which is the same for Boswell and his lifelong friend
Samuel Johnson.
conservation for art is "preserving, fixing, or just restoring old art or other things like artifacts etc." (found in an article on www.msaconservation.com) it's most likely controversial because if something's old and valuable, people want to keep it in it's original form. (just a guess) but that's how it is in the art world.
