To add to this discussion, here's another example that has proved contentious:
Is there an edition of "Life on the Mississippi" with historical commentary?
The chain of comments provides a good range of differing perspectives:
- There are close-votes for this question on the basis that it's asking
for a recommendation (it's not) or that it's an open-ended query "not
scoped clearly enough to accept objectively supported answers of
reasonable length". I think the scope of this question is
sufficiently limited to avoid an open-ended list-type answer and
ensure it can be objectively supported. I'm voting to leave it open.

- @ChappoHasn'tForgotten Asking for recommendations is off-topic even
when asking for a recommended edition of a specific work. See this
question, comments thereupon, its answers, and the discussion in
chat. – verbose
- I feel like it's a factual question, though, as to whether such an
edition exists. – Sean Duggan
- Although, a quick google for "life on the mississippi" annotated
brings up at least 4 different results, almost all "independently
published", with different covers, which suggests that there may be
too many "correct" answers out there. Also, I'm not certain how many
of them specifically comment on history. – Sean Duggan
- @verbose This post doesn't ask for recommendations, it simply asks
for a factual response, viz is there an edition of this specific work
that includes an historical commentary? An answer of "Yes" would be
too short to be acceptable, but an answer of "Yes. A preliminary
search reveals 4 editions that might fit this request. The following
is a brief description of each...." would be an excellent addition to
our Lit.SE library. Do you think this site is being overwhelmed with
such posts? It's not the same kind of question your comment links to.
– Chappo Hasn't Forgotten
- @ChappoHasn'tForgotten The question header is not the entire
question. OP says "I am looking for an edition of Life on the
Mississippi with historical commentary." That makes it just like the
Malory question; neither is a question that has a closed-ended
answer. To argue otherwise seems odd to me. As another comment says:
"there may be too many 'correct' answers out there." If X posts a
list of four such editions, what's to stop Y from posting a list of
another three? –verbose
There's clear agreement that obvious recommendation questions are unacceptable and therefore off-topic. And verbose's thoughtful answer provides an important differentiation between finite (acceptable) and open-ended (not acceptable) list questions. But this meta question points to the critical issue: how do we define "open-ended"?
Peter Shor's answer moves us a bit closer to a solution by focusing on how many "examples" (i.e. discrete solutions to the question) are likely. Peter suggests two potential filters:
- is the number of examples reasonably limited? – in which case the question would be allowable; and
- can "anybody with a half-decent knowledge of the subject area ... think of examples"? – in which case the question should be closed.
Both filters are a reformulation of the "finite" list-question type, the primary assessment being common sense. "Are there any novels in which humans use magic to teleport themselves?" should be closed, as it's too obvious and broad; "Is there a Harry Potter novel in which someone dies due to their incorrect use of the 'disapparate' spell?" should be allowed, as it's specific and limited (finite).
But how do we resolve what "reasonably limited" means? In the Mark Twain question, Sean found four examples with his simple search query, but how do we know whether that's the tip of the iceberg, or whether the specifications in the question actually rule out nearly all examples? Do we need to wait to see what expert answer(s) we get, or do we prejudge the question's scope when we may have little expert knowledge in that particular area? Is a preliminary internet search query sufficient to suggest what action we should take?
These are difficult questions to answer, so I'm going to suggest we go back to what Stack Exchange exists for, and look at how we honour our purpose, maintain the site's integrity and still encourage contributions.
Our purpose: "Literature Stack Exchange is a question and answer site for scholars and enthusiasts of literature. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about literature." [my emphasis]
Common sense dictates that we don't accept "every question". Experience shows that some of our answers are not very detailed. But I reckon Lit.SE has the highest proportion of detailed, comprehensive, authoritative answers of all the SE sites I've been active on (EL&U, ELL, Literature, Writing, Astronomy, Physics & several others). I suspect we might also have the fewest questions and fewest answers of any of those sites. We should take that into account when we consider how strict we need to be on questions that might be a bit open-ended.
That makes me lean towards being a bit more permissive on what we consider "reasonably limited".
Regarding the Mark Twain question, I'd prefer to leave it open. Our Lit.SE library will benefit from this question being answered, but I very much doubt we'll get more than three answers. We might not even get an answer at all.
I think that's a reasonable approach.
