hopefully this different from others but if not dang i didnt read far enough back
but the book goes in study to read and to activate (requires lp income equal to cost of book in order to read)
open book window go to page you want
each page adds to lp cost some more then others based on the use and the book binding
3 types of pages i chould ponder are
advanced crafting recipes (rare crafts, unique versions of more common crafts) click the page will open craft menu (will not show in main menu only way is the book)
building plans (free form building thing) with a survey type thing you can copy some building and remake elsewhere exactly, mabye paveing plan also
then my fav the boost pages i struggled to explain this but ill use example(i open the book to cow meat page anything i craft with cow meat is boosted and takes lp from book (mabye everything chould take lp from book leaveing player unable to spam anything book related)
then each type chould have a book binding that lowwer lp from its type but takes more lp for other types and one general book that just takes everything at same rate
just some thoughts on books
was gonna touch papermaking but my god sooooooooooooo many dif ways and many many more lost unknowen ways had i included that i think it woulda been a far crazyier idea
