Some kind of springtail
Very cute! I know how tiny these are.

Not an expert, but
I would assume this is one of the Elongate-bodied Springtails, in the Order Entomobryomorpha. (as opposed to Globular Springtails, which have distinctly more rounded bodies)

I'm not an expert either,
but it's definitely elongate and not globular.

Possible Elongate-bodied Springtail - Thanks Ash and Dan
My first thought was it looked like a Springtail, but I didn't think one would be in a musty book so I crossed that idea off. It could have hitched a ride inside I guess.
It ran back and forth around the page, didn't seem to have a spring in his tail.
Looks a little like this one except this one is a lot larger:

From what I know...
They can exist virtually anywhere with moisture, so this little guy could have been eating mold in your musty book. According to this University of North Carolina website, there are 677 known species of springtails in the US alone, so I doubt bug guide has every species represented. The "spring tail" from which they get their name is kept under the abdomen, making it difficult to see, especially on such a small creature. The following image captures it well though:
