I have an Amazon wishlist with something like

70

categories just for books (mostly eBook, sometimes both print and eBook). Perhaps I have gone too far?...
My lists include everything from classics to horror to ghost fiction to SF/fantasy to domestic suspense to BookTok favorites to books about books. Some categories have just a few eBooks, and others might have dozens or (ahem) hundreds. At least a couple of lists have more than 1,000.
Maybe I should export my wishlists?... Just in case?...
