[ WP ] You 're an accidental time traveler trapped in the 14th century with a twist ... you 're just a librarian , what do you do with all your knowledge ?

I went to pretty prestigious public university for my undergrad, and I took a fairly diverse range of subjects, so I had friends from all major, including ( thanks to my love of biology and math ), a lot of premed students and engineers. 
 
 They all said I was brilliant, and some of them laughed when I told them my career plans. I was so smart, why should I want to be'just a librarian'. I shook my head and told them they would n't understand, although perhaps I just did n't want to explain it. 
 
 Even if I had n't been sent back in time almost seven hundred years as a result of a physics experiment gone either perfectly or massively awry, my work still would have mattered, because there's no such thing as'just a librarian'. 
 
 I am more than a mere keeper of books. I am a Master of Information without peer. I've run programs teaching people about subjects ranging from Middle English history to modern farming techniques, to cartography. 
 
 So, when I arrived in fourteenth century England ( and I knew where I was and when I was based on the local flora and the talk of war over an English king claiming the French throne ), I was prepared. 
 
 In many ways, I was better prepared than any of my highly specialized friends. 
 
 My ex-girlfriend Michele, who went on to be a fairly accomplished surgeon could probably stitch a wound far better than I could ever hope to. But I doubt she knew how to make stitches from catgut or silk, as I did. 
 
 My former roommate, Alex the mechanical engineer, could probably make machines with tolerances well beyond my own, but could he teach people who to refine iron into stainless steel? 
 
 Could any of them speak enough medieval Latin to communicate? I doubted it, even among my own profession that was an obscure skill that I was mocked for learning. Joke's on them, I guess. 
 
 So, with a spring in a step and a gleam of ambition in my eye, I headed to the coast to find a ship to the mainland. I would have to earn money along the way, but being a literate person, I could pass for a wondering priest and collect alms. 
 
 I would need something that I could pass off as a bible as I preached to people, but that would n't be too difficult. Some scraps of leather and a cloth would fool most people. 
 
 Once I reached the mainland, I would head for Rome and establish myself as a part of the Catholic church. I would have to turn the Roman Catholic Church into a monotechnocracy, declare the Avignon popes heretics and excommunicate them, and set myself up as a dictator, but that should n't be too difficult. It was n't like the church was n't headed for another Great Schism anyway. 
 
 The Black Death was coming up, but that was nothing a few good lessons in hygiene, quarantine, and the early invention of the chlorine bath could n't stop in its tracks. 
 
 On that subject, it would probably be a good idea to kickstart chemistry entirely and introduce the periodic table a few centuries in advance. 
 
 In order to explain all my strange knowledge, I would have to claim to be a new Messiah sent by God at some point, and dodge the inevitable assassination attempts, but a little biological warfare in the form of plague infested blankets in the right houses, followed by claims that God had sent the pox as punishment for their heresy against me, his new prophet, would probably head off the worst of that. 
 
 Then it's just a matter of writing down enough that my successor, whoever he or she might be, knows what to look out for. 
 
 Like global warming. If the industrial revolution happened fast enough, followed by a rapid conversion to nuclear power, that problem might be prevented entirely, though that was far enough in the future that I was n't too concerned about it. 
 
 Right now, I just had to remember my history. 
 
 After all, I was making it.
