I was recently playing around on Etsy and came across a listing for some old library checkout card pockets. Remember those? The little manila slots that the library checkout cards were tucked in to? Those were the days prior to scanning bar codes, when searches were done by card catalog and book checkout consisted of the librarian stamping a date next to your name on one of the cards inserted into a pocket inside the cover. I have a soft spot for this type of nostalgia. It is odd to think that my kids aren’t going to know anything other than a computer search and a zap with a scanner on the way out the door.
