Register.

For a century, figures about Africa have travelled one way: gathered on the continent, priced in London and New York, and sold back to the people they describe. This market closes that circle. A reader who holds a table worth consulting offers it; the house reviews it under the method and publishes it, attributed and dated, beside its own rows, never merged with them. Prices are set at the purchasing power of the continent's own researchers, on three shelves; each table prints its price on its row, and the full schedule of everything this house charges lives in one place, the access terms. Seventy percent of every sale returns to the contributor, roughly double what the large content marketplaces leave their creators; the thirty percent that stays covers the payment desk, the review, and the register that guards everyone's proofs. Use is rewarded as well as sale: every appearance of a table in another reader's search is counted, and a quarterly pool, ten percent of readership revenue, is shared pro rata among the most consulted tables. The full table releases only after the house verifies the payment. Data made here earns here, and what it earns funds the instrument that keeps it verifiable.
