~ gathering the most-loved ~
Start with your library — a Goodreads or StoryGraph export uploads whole — then answer the only question that sorts a bookshelf honestly: of these two, which did you love more? The tiers assemble themselves.
A Goodreads or StoryGraph export fills your shelves in one upload.
Two books at a time; each answer files one into place.
Loved, liked, disliked — with a true order inside each, not a heap.
Five stars flatten a library; even half-stars just make finer mush. Tiers with an order inside them are the version of a bookshelf you can actually argue from.
