I recently found this question
which is currently deleted (screenshot). I'm not sure it's a great question but it seems to matter to some people. When it was closed it was off-topic by the then-current
books policy, but it is now a fixable question. I'm not sure why it was deleted - is there something I'm missing?
Ideally, this question should be undeleted, have the books banner added, and have its answers collected into the usual CW collection.
