There is no shelf.

Well, except for the ones on which my old school book collection resides. Here’s an interesting video about the ways we store and handle information.

Creator’s description:

“This video explores the changes in the way we find, store, create, critique, and share information. This video was created as a conversation starter, and works especially well when brainstorming with people about the near future and the skills needed in order to harness, evaluate, and create information effectively.”

It also references Dave Weinberger’s Everything Is Miscellaneous.
