This short film is up for an Academy Award and for good reason. If you love books even a little then you need to watch it. I got a flashback to that one scene in MirrorMask (you'll know it when you see it), which reminds me I need to rewatch that movie. This film is sweet and moving and I just want to wrap myself up in it.
Like the description says, it's about "people who devote their lives to books and books who return the favor." Go, watch, be made incredibly happy.
