Counting the uncounted: a mark-recapture census of the Sahel library

Status: Anticipated · untested

Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

Timbuktu's manuscript world has been sampled twice by partly independent digitization efforts — organized library digitization on one side, family- and region-based field projects on the other. Where two independent samples of one underlying population exist, ecology's mark-recapture logic applies to books as well as to fish: the overlap rate between the distinct WORKS captured by the two efforts estimates the total number of works in circulation, catalogued or not. This conjecture claims the estimated total of distinct pre-1500-composed works that circulated in the Sahel is at least three times the number so far catalogued — that is, the Sahel blank is predominantly type-5 missingness (uncatalogued, undigitized) rather than type-1 (destroyed). The size of Africa's unread library stops being a rhetorical flourish and becomes a number with a confidence interval. If it holds, cataloguing — not excavation and not mourning — is the highest-yield act available for pre-1500 African intellectual history.

Prediction clause (verbatim)

Primary clause: applying a Lincoln-Petersen or Chao estimator to distinct pre-1500-attributed works appearing in vHMML African holdings versus the EAP West African collections, the estimated total is at least three times the observed union, with a confidence interval excluding 1.5 times. Killed if the overlap between the two samples is so high that the estimate approaches the observed union — near-complete cataloguing, meaning the blank is real loss after all.

Kill-dataset (verbatim)

vHMML African holdings cross-matched with the EAP West African collections.

Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior. Kills and priors are credited here, by name, as they come in.

Provenance

Run: Fresh agent generation · model: claude-fable-5

Generated blind by a fresh claude-fable-5 instance in a single Write with no reads, web access, database queries, or other tool calls.

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

The method is published prior art: Kestemont et al. applied unseen-species/Chao estimators to manuscript survival in Science 2022, and the qualitative claim that catalogued West African material is a small fraction of the whole is also in print. The two-independent-digitization-samples design for the Sahel specifically was not located.
