# Is asking for references OK?

Or should only substantive questions be allowed?
If not, is there another place to ask reference questions?
Actually, I would like to ask reference questions, so I will make this a feature-request,
even though it began as a simple request for information.
I would be quite happy if reference questions were kept in a separate location or category.

• Also, what kinds of questions do you have in mind? – David Z Jan 23 '11 at 0:06
• I think it should be okay. I had some questions of this sort that I haven't asked because I wasn't sure they were proper. This would be things like "What was the first paper which gives the solution to the obscure and little known xxx problem?" With tags, it should be solvable. – Carl Brannen Jan 23 '11 at 0:31
• can you provide some examples of such reference questions in your question? It's hard to understand what exactly it is you are asking, without examples. – Jeff Atwood Jan 23 '11 at 11:21
• For example, I published a paper that gave the force of gravity for a non rotating black hole exactly in Newtonian form. That is, I showed a Newtonian force system whose orbits were exactly those of the Schwarzschild solution in Schwarzschild coordinates. (And I also did the Gullstrand-Painleve coordinate problem.) I had a conversation with an old GR prof and he hinted that it had been published before. So was it or not? – Carl Brannen Jan 31 '11 at 22:32
