I would love the ability to have representation tagged by the amount and quality of representation, kind of how it is with content warnings. Users would be able to tag books they’ve read with the representation they include (and how much of said representation they include) and other users would be able to search by representation. I’m always looking for books with good anxiety representation but it’s hard to search for. Similarly, I’m always looking for middle grade books to read (so I can recommend them) that match the identities of the young people in my life.
