Making sure your reader sees what you saw on Wikipedia
It’s valuable, it really is, I point to Wikipedia articles regularly, but always with an implicit caveat. I can’t be sure that the article I point to today, that I believe is accurate today, will be accurate tomorrow.
Ah, but you can.
Click on the history tab, then click on the most recent date. It gives you a URL of the version that is current, so if it changes in the future, you will still see the version that you were looking at today.
It even shows a set of links to navigate revisions.
For example, the current, as of May 25, Diffie Hellman key exchange.
But this is actually a problem for the Internet as a whole. For example, how do I find out what a Google search would have shown me a year ago vs today. Do they keep that kind of data?
