Echoing the Physics Meta question on this topic, does Math.SE have the will and use case for building a community list of books? Such a list has successfully been curated on the Physics.SE, and I would honestly appreciate this for mathematics. The Math.SE community has discussed the need for tags, and there does exist a
book-recommendation tag. One can also see that there are numerous questions requesting for book recommendations on a variety of subjects. These observations suggest to me that there might be a want and use case, but I would appreciate the perspectives of others that have ideas about this option.
Do we need/want an overarching books question?
