I know I'm fairly knew here but my big thing in any video game is honestly purely achievements. So as an achievement whore, one thing that becomes very useful and I know many other achievement go getters like to have is pictures. But for this game specifically, some of the most tedious grinding can be the lore books and world books.
What I know would be helpful for anyone using a wiki to find achievements is to have pictures of the map for each book marked with the spawn points. Best example I can think of is the Hanging Tree book in Act 1 before the cemetery. There are I believe 3-4 different spawn locations, that can easily be marked on a picture of a map.
Just my input, hope im not stepping over any lines here
