We have a huge library of research books to pull from, so this isn’t a complete list, but we’ll try to keep it updated with our favorites.
General GI Books
GI Collector’s Guide: Army Service Forces Catalog, U.S. Army European Theater of Operations Vol 1 and
Government Issue: U.S. Army European Theater of Operations Collector Guide Vol 2
These books are currently stupid expensive, but amongst my favorite general research books. They have their share of mistakes, especially with commercial personal items, but they’re the most comprehensive books on gear and equipment that I’ve seen.
Quick disclaimer: All the links point to Amazon. We do get a very small percentage of the sale.
