In a question I asked I would like to show the relevant page in the comic book. Is this allowed, and if so what citation should I use? I have it scanned in a jpeg format.
I Am Not A Lawyer but this seems like fair use to me.
In US law, that means there are four important factors to consider:
- Purpose and character of the use
In this case, it would most likely fall under "for nonprofit educational purposes".
- Nature of the copyrighted work
Not really an issue here; it's not something that ought to be in the public domain.
- Amount and substantiality
Just one page, not the whole book.
- Effect upon work's value
It's not likely to decrease the value of the original work; one could argue it would increase.
Other jurisdictions often have similar provisions to allow quoting.
On this stack, we have a number of questions, like one about covers of comics, so quoting a page is nothing unusual.
In general, if you would have a hard time asking your question without it, it's probably okay to add it.
