I have a couple specific questions about the word tree vs. book in Rev. 22:9

There is such a large amount of information on the net, it's hard to get a straight answer.

First, could someone please tell me how many existing Byzantine texts that use the word tree? And how many use the word book?

It seems that there are more than 5000 Greek texts out there, and I assume that those which contain Rev. 22 in it's entirety are many fewer, but I haven't been able to get even an approximation of how many are out there.

This was my main reason for signing up. I am not totally new to textual debate, but my level of knowledge restricts me, in that I don't yet know where to look for reference material.

Thanks
Tim V.
