History Question 2

I've been looking everywhere for people who wrote/got shortlisted for History Q2 (the one about the Library of Alexandria) and have barely found anybody. I found the topic so interesting, but when writing my essay, I ran into so many roadblocks because of how old so many of sources were! I'm wondering what everybody else who did this topic decided to do for their thesis. I ended up doing that it'd be a big impact, not from the actual knowledge that is circulating, but the weight of the knowledge (intellectual authority), and how both it's loss and existence shaped knowledge transmission. Basically how one theory would have more precedence in the academic world than another, and how that shapes how we learn and grow as a society.
