I got into a habit of screenshotting and printing (more like save to pdf) anything that I find important.
Too many times I found that an event that was in the news few years ago and suddenly is relevant today has been scrubbed.
(For instance a certain doctor hosting a conference sponsored by a pharmaceutical company, then few years later same doctor, now promoted, blocks prescriptions of certain drug that would otherwise cause said pharmaceutical to lose money, at the expense of patients - no longer can find evidence of the event online).
