In the words of my prof, "Y'know what, sometimes the curtains are just fucking blue... but we don't read trash in this class. So when the curtains are blue--it means something."

(And no, he didn't mean to make stuff up about the sybolism of blue curtains and snowballs-- he meant, that good books are meaty with ideas. They tell you about the values, the era, they tell you where the characters are coming from. They paint a meaningful scene when taken as a whole.)

Please do not do this. One of the fundamental keys to conserving books is to maintain even heat/moisture. Baking books in a home oven is not only a massive fire risk due to the nature of the heating element, but you will shorten the lifespan by a lot. Old book pages already get crumbly when they lose moisture over time. Do not hasten the process by further removing moisture and exposing it heat. You will also damage the binding, melt adhesive, etc. this way.
