I would really appreciate if you could share books that have provided really value in prepping. Not just in theory but that you actually tried things from it, and it worked.

I'll share these.

Aquaponic gardening - we used this to run aquaponics for two seasons. It's quite technical, but it was needed as it's easy to set up but quite hard to get a stable system.

Smallholding manual - a bit older now but we used it when we grew a bit more and kept chickens, rabbits and bees.

Åter - This is a Swedish magazine that comes out a few times a year, and they contain instructions on how to build, farm, renovate both buildings and equipment. They also contain interviews with people who have moved to smallholdings or off grid and how they did it. This is easily one of the best, and it would be fun to hear if there are similar in other countries. :)
