There are a few questions regarding books (actual books, not answers that could stand on its own as a book) which are either closed as "not constructive" or still up for debate (and might possibly be closed).
The close description for "not constructive" is as follows:
This question is not a good fit to our Q&A format. We expect answers to generally involve facts, references, or specific expertise; this question will likely solicit opinion, debate, arguments, polling, or extended discussion.
I'm proposing that the criteria listed here serve as a starting point to determine whether book questions should be closed or not.
- Recommendations for resources
- Reviews of books
- Questioning scientific validity
In the last case, those type of questions may be better suited for Skeptics.SE, but depending on how the question is worded and what it is actually asking, this may be debatable and probably handled on a case-by-case basis.
- Is the book "Wheat Belly" credible?
- Fiber Menace - How scientific is this book?
