much knowledge this man does have.
You never cease to amaze me and I hope you never do!
You are sweet Lady. Note the capital L.Doing your own research
The easiest method of doing research is using Google Books. Many prepping topics are esoteric. For example, let's say you were looking up Native American tribal lore on medicinal herbs. There's probably a handful of ethnobotanical or medical or arthropological studies done, but it's difficult to find them. I've found many through Google Books, and often if old then they include the whole ebook. Not only that, but also the value is that it's searchable too versus straining your eyes looking through pages and pages of dusty tomes. Believe me, my hardback library is enormous, but many times I can quickly find an answer from this research.
Google Scholar has much more authoritative links to research, but often they only point you in the right direction. What you can do after that is see if your library has a membership in any of of hundreds of academic databases like EBSCO. Usually you can do those searches online as well, so you can look up some rare study about a topic.
archive.org has free ebooks on it in which the copyright has expired. This means that you can download thousands of books for nothing. Likewise Project Guttenberg has thousands of books for free in this category.

Realize that old information is not necessarily valid. You have to continue to research and ensure that it is. In many cases someone picked up the baton, and like a relay race carried the research onward.
Having a resource library is crucial. These documents can downloaded and stored on a USB hard drive. This means that you could potential recover them at will and this would be among your treasures.
You might be the only person in your community with that knowledgebase. You might end up becoming a community leader or teacher or shaman.
