As per our FAQ, recommendations are off-topic. Historically, we started off allowing them, but eventually banned them. At the time, it seems that our analysis was that most recommendation requests were really list requests, which are a category of their own, and the others are personalized and thus too localized.
Fast forward to this question, which is mostly asking for an explanation of a trope in SF works. That comes with examples, but they're meant to illustrate a point more than being recommended reading per se. There's some disagreement as to whether this is a question we want.
On a related note, the Literature site (now defuct) tried out book recommendations with a limiting policy that tried to allow the worthwhile questions and reject the ones best suited to wikis or chat. The site eventually failed due to low traffic; it doesn't seem that book recommendations was a significant aspect of that lack of traffic. Since the site is now close, I quote the policy here:
- The questions must be reasonably specific. Not "What's a good book for a person who likes Harry Potter", but maybe, "What's a good book for a 13 year old boy who likes Harry Potter, Eragon, Percy Jackson, and Artemis Fowl?". The more details, the better. Otherwise, how could you expect someone to possibly answer?
- Answers should try to recommend as many relevant books as possible. Aim for a syllabus, not for an evening's read.
- Answers should provide some reasoning on why a book is suitable. Don't just say “read this”, explain why. [If you can't motivate why the book is suitable, consider leaving a comment instead of posting it as an answer. Answers that do not meet this guideline may be removed. --Anna Lear]
- This is not a popularity contest. Votes should go to the answers that provide the best match for the request. Don't vote up or down because you liked or didn't like the suggested books.
- Close any question which does not meet these guidelines. The number of votes is irrelevant when deciding whether to close a question.
- Should this question be closed or opened for reasons that have nothing to do with book recommendations in general?
- Should we revise our stance on book recommendations?
