Deleting old set of books

[David Both]

I have two old sets of books that I have used for testing certain entries for my 
business books. I also have two sets of real books, one for my business and one 
for my personal finances.

I have finished with one of the sets of test books and would like to delete that 
set of books. I can find no way to do that.

Question 1: Can anyone tell me how to delete a set of books?

Also, having used GnuCash for over 13 years, I have many old transactions 
hanging around.

Question 2: Is there any way to prevent display of transactions that are more 
than, say, 2 years old, or some other arbitrary age, while still maintaining the 
integrity of the books? This would also require some way to access older 
transactions if required for some reason.

Thanks all for a great program!
