I loved these as a kid. My elementary school library had most of them and I read every single one.

Arms and Armor was my favorite because I was a weird 8 year old boy and weapons are cool. Then I tried to search for more books about guns on the computer in the library.

I got in a heap of trouble and I thought it was so stupid. They had one book about guns, why couldn't I look for more?

Oh by the way, this happened right after Columbine.
