Under what circumstances is acceptable to email an author questions? Let me give some examples of different circumstances:
- some experiments were performed, but not all details were included.
- I (the reader) don't understand a certain detail about the paper.
- Asking for more details about a particular procedure.
I know this is not a black-and-white matter. In fact, is there even etiquette on when to email or when not to?
If it serves anything, I am asking from a STEM perspective.
