I have heard many get the bigger books to steal from. Take part of 1, part of another, and then put it into a homebrew.usually people want a book because it activates their imagination
But, plenty of people do buy smaller, or DM Guild would have been shut down long ago. AL is shorter, and DTRPG is mostly catalouged by shorter products, not epic Worlds Largest Numenera books.
