At one point I'm at a shelf and pulling out thin volumes with titles like (remembering poorly) "Shift calculations of blah blah style concrete," "weather effects on bloo blee cement," "compression formulas for heehaw company concrete," and so on. Book after book. Next shelf, same thing, entire volumes of concrete and cement research and data. All with different titles, different content, different authors.
As I moved down more I realized the entire row was books on concrete. How? was all I could wonder. How could there possibly be this much published information on concrete? Who dedicated significant amount of time to compile research, stick it in a thin volume, and then have it placed among a thousand others? What librarian chose these books?
I had a mild plan when going into college of reading a whole lot of everything I could get my hands on, but it was only then that I really grasped just how much information is available to mankind. It's truly unassailable. (probably relates well to the other article on the front page right now about the last man to know everything)
