Back in the day, about thirty years ago or so, when you checked out a book at the Claremont Library (a branch of the Los Angeles County Library system), they looked up your name on their rolodex. You wrote your name on the card in the book pocket, they stamped the due date in the book and on the card, and maybe you made it home before you started reading your book. Maybe you didn’t.
Then, at some computerized point, you were issued a plastic card. The first ones were black, like these. Now I think they are green. This one has seen quite a bit of use. But I miss seeing who had checked out the book before you.
