This is another interesting resource from the US Department of Agriculture. This is a fairly comprehensive guide to canning food on individual basis. While the skills outlined in the book are not directly related to the outdoors, the preservation of food is an important skill, and has held great significance throughout history. As such, I thought you guys might be interested in it.
To the best of my knowledge this book is in the public domain, and a copy can be obtained here, here, and a number of other places online. The book has several chapters, which can be downloaded as PDF files individually.
