History of Flip Books? Need some info.

Anyone know where to find information on the history of flip books?

I'd like to know this history from 3 perspectives:

- Role in early animation/cinema history.
- Use as a "pop culture" promotional item
- Collectibility today: flip books as a collectible

Any "leads" you can provide to point me in the right direction to
research this topic would be greatly appreciated.

Thanks!!!
