Yeah, I have curated my library to be focused on the history of science, with special focus on the sorts of books which include information necessary to bring society to the technological equivalent of the age of reason (with extra chemistry and medicine). At that point, it’s mostly practical, and the practicality of the source speaks to the likely authenticity of other texts within the collection.

Congratulations, you’ve just written a quarter of the plot of the Book of Eli with Denzel Washington
