When looking, I find stuff that my brain sorts into “keep” or “reject” piles. I click, I e-mail, I save, and an hour later, I could not for the life of me tell you what I was looking at. Reference desk, personal research, doesn’t matter.
When I putz, I am much less efficient, but I find awesome stuff like this: Debates in the Digital Humanities.
