The thing with that is it's still a digital catalog of sorts. Using tags, subjects, etc. from others, often doesn't provide a randomness.

The nice thing about the library is that I have topics ordered by author, but as I browse, I don't always go by author. I walk and my eyes may move up and down, I may skip whole sections, looking for a shape and size, color, name, or picture that catches me eye. When I do that online, I tend to still get stuck in a very narrow filter bubble.

The analog world creates a randomness that I'm not sure is easy to deplicate on a computer.
