I’m enamored of the 500s (science) in general, but the 590s are really a favorite. Biology has always fascinated me and public libraries tend to be delightfully skewed toward whole-animal observation-based books (as opposed to the more reductionist biomolecular focus that’s more typical, I think, of current research). I love this kind of reading, as it makes me pay more attention to the wild world around me– even if those wilds are just the neighboring woods.
