Oh my god. You know at school, when you read stuff in a textbook and just accept it as gospel? That’s what I was doing with all the academic papers I’d been given to read at university. BUT! I’ve recently discovered it’s possible to see what other people have said about them and how they’ve used their work, and on PLOS it’s even possible to see short comments on different papers. I’m a total citation history addict now, it feels like the newly discovered universe of academic learning has just opened up further and is even more vast and fascinating than I first imagined! Woo!
