Questions tagged [specific-reference]

Use this tag for questions seeking a single specific paper or a short, non-open-ended list of references, like "What paper first discovered X?", "Where can I find the original derivation of X?", or "What is the canonical source for X?" etc. Also for requests for hard-to-find electronic copies of resources when the exact reference is known. NOT TO BE USED for generic requests for resources (use [resource-recommendation] for that).
