More specifically, Mending books. I've already lost 2 sets of armour in the end, and I'm done. I'll just go back to my fish farm. List a price (in diamonds!) and I'll see what I can do. On the other hand, would anyone be interested in enchanted book grab-bags or similar? Pay X amount to get N books? I... will probably never get around to doing that, as that would require lots of time spent at the farm that I don't have. But hey, gauging interest.
