When referencing previous results, should one cite the original paper(s) or a recent comprehensive monograph?
Specifically, in my area of interest (a relatively recent branch of mathematics), in the last ten years, several monographs have been published (by different authors) which cover (virtually) all "classical" results and most of contemporary developements organizing them, putting them in their context, and offering extensive references to the original papers.
To clarify my position: for the sake of "culture", I've read a few of the original papers in which the results I use most often appear for the first time; however, for the benefit of the reader, I'd rather cite only the most recent (and most comprehensive) source (and possibly point the reader to the additional references therein); in my department, there are researchers following either policies.
