Most times these books are only free for a day or two, so you have to grab them while you can. Worry about whether you really want to read it later if it seems interesting. And be careful, they can change from free to not free at any time. I have also decided to list books for no more than 2 days in a row to avoid cluttering up the posts, unless there is some reason I think the book deserves extra attention.

$10 Root Cellar: And Other Low-Cost Methods of Growing, Storing, and Using Root Vegetables (Modern Simplicity)
1/10 of an acre can feed you all year!
The easiest way to grow more of your own calories is to focus on roots like potatoes and carrots. With yields of up to 200 calories per square foot, you can break your reliance on the grocery store with just a few seeds or starts and a shovel. Most root crops are easy to store through the winter and require no special harvesting or processing equipment.
So why don't we all grow roots? To keep them happy after harvest, these crops need a cool, damp storage spot like a root cellar. This book walks you through building a root cellar out of a junked fridge for $10, and also presents some slightly-higher-cost options for winter storage. Other highlights include tips for growing storage vegetables and feeding those roots to your family or your livestock.
Self-sufficiency begins with the potato!
