YouTube does have a wide array of pond related videos, but I would rely on known companies or experts. Aquascape has quite a large selection of YouTube videos. As to books, I have only 2 recommendations: First, and most important, is a basic comprehensive book on Freshwater Biology, and secondly, Rick Bartel's "The R.I.S.E. Method". After that, participate in Forums (such as this one). do your own research. Keep in mind that you will frequently discover--conflicting ideas and claims, experts can be wrong, cheaper is not always better, and contrary to the pervasive arrogance of man, you can't improve on Nature.
Almost forgot, another good book is "The Pondbuilder's Bible" from Aquascape.
