I had a Collection I made that worked fine. Then I added in a 2gig SD ram card. That also works fine. But if I put a book on the SD card, I cannot put that book in the collection I have. Is there a way to do this so I can have books on the SD ram and in collections as well?

Unfortunately, you can not. A major limitations of the Reader software is the inability to maintain collections of files that are on the memory card.

This is one of the most requested features - maybe SONY will pay attention.
