Are there any specifics about what you’re interested in? There’s sooo many recommendations I think if you had some cultures or areas you were interested in, that might help!
Like, if you’re interested in the many cultural versions of Vampire or Dragon folklore, I’d recommend something wildly different than if you were interested in Greek or Norse Myth.
For starters, there’s the encyclopedia of Folklore and Literature and the works of Thomas Green (he’s got more specific stuff on various cultures but I linked to the two volume encyclopedia, or at least to one of the volumes of it) There’s also specific stuff I could recommend, from Japanese ghost stories to Irish Fairy catalogues to compendiums of Goddesses and so on. So if you get a bit more specific maybe I can recommend some others
