This probably also could go to English.SE, but I'm not sure.
When I want to cite a source for a complete sentence, you put the citation before or after the period?
And if you cite for a word, or figure, do you put it before or after the comma?
Please bear in mind my citations are not superscripted, here's an example:
appropriate awards and punishments[4, p.415].
appropriate awards and punishments.[4, p.415]
when, on January 28[3, p.4],
when, on January 28,[3, p.4]
I have a feeling that for facts I should put it right behind the fact and before the comma, while for sentences it should be after the period, but I do not know for sure.
~) before the reference!
