The FAQ states:
But please, don’t ask any questions about these topics. They are out of scope for this site.

- general reference
This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.
It might be good to have a list of such general references. Perhaps it could be posted on the FAQ; in any case, if a question is closed as general reference, it would be great if we could link the OP to this question so he could find the answer himself the next time. I think this would reduce a lot of the general reference questions asked on EL&U, as well as enabling people like me who don't know much beyond dictionaries and thesauri to more intelligently search.
