I believe there are two roots that feed the rare soul scene. The first is the collector of original issued recordings, gaining knowledge of what is available, and making or breaking the reputation of records, which may then become desirable and even canonical. The second are the archivists and researchers, like Ady C and Tony R and the other Ace boys, who enrich the available stock by discovering new stuff, and who also give the genre credibility by by giving the sounds an historical context.
