I’ve started to keep the first page of each academic paper that I read in a binder, marked with my notes about the paper’s content and usefulness. I started doing this in June 2014. Between June and December, I read 89 academic papers. In January and February 2015, I read 69 more.

By Decade:
1980’s: 2

Total citations among 69 papers: 18,108
