Query: AN EXECELLENT BOOK THAT KEEPS YOU UPDATED ON GUNS & AMMO

GUN DIGEST IS AN EXCELLENT PUBLICATION ABOUT GUN & AMMO THAT IS AVAILABLE IN THE MARKET TODAY. I HAVE BEEN BUYING THIS BOOK EVERY YEAR SINCE 1980. DUE TO MY PREOCCUPATION I MISSED 1988, 1999 & 2000 EDITIONS WHICH I SHALL ORDER VIA THE INTERNET THROUGH AMAZON.COM. THIS BOOK WAS HELPFUL IN MY CAREER AS IT EXPANDED YOUR KNOWLEDGE MORESO WHEN I AM SO FOND OF HUNTING & SHOOTING.
