Knowledge is actually hard to lose nowadays
A Point of View: Why didn't Harry Potter just use Google?
In a world that is overwhelmed with ways of accessing information, we must decide what to remember and what to forget, says historian Lisa Jardine.
The danger today is rather that we are reluctant to let go of any information garnered from however recondite a source. Every historian knows that no narrative will be intelligible to a reader if it includes all the detail the author amassed in the course of their research. A clear thread has to be teased from the mass of available evidence, to focus, direct and ultimately give meaning to what has been assembled for analysis. Daring to discard is as crucial as safe-guarding, for effective knowledge management and transmission today.
