Free/inexpensive koi pond books

I've came across some books on pond building. As these are some of the most important steps to do correctly before you can buy your koi. The bulk of the work actually comes before you even buy koi. You have to figure out what size pond, where to locate the pond, amounts of shade, how to build a filtration system...much more

Thanks to the awesomeness of the internet. Some of the books I've actually use can be found online and are either free or very inexpensive if you buy them from Amazon for your kindle or book reader device. If I had discovered this source to get my books, I would have saved a lot of money. Here are just three of the ones I've used:

Water Clarity Secrets for Ponds and Water Gardens: The Quick and Easy Way to Crystal Clear Water
A Practical Guide to Building & Maintaining Your Pond 
How To Perfect Your Water Garden with Pumps, Filters and Water Features
