It's hard to imagine that people would want most of the things in the collection. Not sure what someone would do with a good dental report from a few years ago or an old Southwest luggage tag. But among the finds there are a few items that people would find priceless, like old family photos and little love notes.

McKellar told NPR that she had been collecting things from library books for a while, but about 10 years ago she figured other people may also find the items interesting. That's when she started adding images of the found items to the library's website. Other Oakland librarians send things they've found in books to McKellar, who then scans them and uploads them to the website. When speaking to NPR, she said, "I had always collected little things I'd found in library books and I knew other people did that too," McKellar said. "So that was how it started. It was pretty simple, I was inspired by a magazine called Found Magazine."

There are now more than 350 items in the archive, according to NPR, and most remain unclaimed. There's no indication of what will become of the collection in the future or if McKellar will continue to collect until she needs to take out a storage unit. Either way, these little finds are a fun and wholesome glimpse into the lives of strangers.
