@Angle there are actually 2 subproblems here. In neither case are you solving suffering alone.
1) The problem of distributing books, and you getting access to books. You can help with this, by helping to transcribe existing books into digital text, and putting said books on hard-to-censors platforms like #tribler
2) the problem of rewarding the authors
You can use https://villages.cc to allocate trust to said authors, and then look for ways of improving the lives of the people around you.
