A sourcing-provider-implemented, electronic-commerce, communication-network method for controlling acquisition-access to electronically-deliverable, affinity-interest deliverables in portions of which rights are held both by a sourcing provider and by a contributing network communicant. The method includes (a) establishing an electronic, network-connected, sourcing-provider-associated-and-controlled catalogue designed to contain at least one such deliverable, (b) vetting the entrepreneurial talent of at least one network communicant relative to the creation, catalogue-placement, and network-acquisition-promotional offering to others, by that one communicant of such a deliverable, whereby, through deliverable-creation and catalogue-placement thereof, the vetted network communicant becomes a contributing network communicant, (c) authorizing the vetted network communicant to become a contributing network communicant, and to create, to place or have placed, and to offer to other network communicants, deliverables-acquisition network access to such a catalogue-placed deliverable, and (d) rewardingly incentivizing such offers.
