I went ahead and got a #library card.
Although I've checked out books before, it's been a while, and I was a little taken aback by the self-checkout. It felt kinda like that one SNL sketch for the store where you could just walk in, take stuff and go: I was glancing around a bit...tensed up just the slightest amount as I walked through the RF tag sensors at the door...checking to make sure I got the email receipt to confirm it's all good.
Perhaps a reminder of how radical the ethos of a public library is in a world where everything costs money.
