Reading All About Signs

While pondering how to finish updating my proposal I found some promising books on signage at the library. 

Signage Systems & Information Graphics

Pictograms, Icons & Signs

Sign Design (Can't find link)

Sign Graphics

I've got them checked out for a while so if you'd like to take a look at any of them let me know.

I've focused my research more on motion to enhance or expand information in relation to signs. That's rather wordy and I'm trying to work on it, any suggestions?
