I have 2 versions of that "Great Book of Modern Warplanes." The later one with revised stuff I've read far less than the original.
I still laugh when I look at the "unknown" MiGs in there. I love the one that looks like it's halfway between a Fulcrum and a Foxhound, but I forget whether they called it a 29 or a 31.
I've been bringing a book to school, and then work, since 6th grade. In the intervening decades I've read hundreds of books, if not more. Well, as I reread ones I like, perhaps not more UNIQUE books, but if you count the number of times I've reread Lord of the Rings, that Warplanes book, Red Storm Rising and Hunt for Red October, my Gulf Air War Debrief, 2001, Foundation Trilogy, etc, it probably totals well up there.
