Alan Briscoe has done a lot of research. He shares various plans for food storage which is helpful since there is not one plan that will work for all people. I was able to look at all of the plans, and create a unique one that works for my family. His lists helped me think of items that I had not considered before. I love how he encourages the gathering of small cannned goods and boxed packaged food items, as well as medical supplies. There is also a great building plan for can rotation food storage shelves on pg. 49. This book is a little bit older than others and has less than 100 pages. But it is still a great book to have as a resource if you are serious about studying food storage.
