Is asking for references to criticism/essays/articles/etc. relating to a specific piece of literature on topic here?
I went ahead and asked such a question on the main site: Is there much critical analysis of "The Hunger Angel"?

I'd say it depends on how specific your question is.
What are some good essays/articles offering literary criticism of War and Peace?
This would be off-topic as a recommendation question.
[specific question about War and Peace - e.g. what is the symbolism of X, or does passage Y suggest Z]
Are there any existing essays/articles which analyse this issue?
This would be fine. You're asking about what you actually want to know, so that people can answer that question directly if they want to, but you're also asking for references to existing writings on the topic. (Another possibility would be to ask your question without explicitly requesting reading resources on the topic, but to require that answers quote from existing published commentary rather than just coming from the answerer's head.)
Are there any existing essays/articles which analyse [specific issue as above]?
This middle-of-the-road approach is one I'm not sure about. It might be closed as a recommendation question like option 1 above, or it might be treated just as kindly as option 2. You might also be accused of falling into the XY problem - what you really want to know is the answer to that specific question, but you're asking for reading resources on it rather than just asking your question - and so you might end up just editing this into version 2.
