Bolt action rule books

As we all know books are not cheap from anywhere. I have and probably everyone know that warlord like to put unit rules in as many books as possible and I am not wanting to get a book for just a couple of units. So I was thinking if we all say what books we have then we can look at photocopy the odd page. for each other to save the cash.

I have:
United States
Army of Italy and the axis
Imperial Japan
Campaign New Guinea
