The theft that made the catalogue

Claim (verbatim)

When Colonel Louis Archinard took Ségou in 1890 he seized the library that al-Hajj Umar Tall's Umarian state had assembled — some four thousand Arabic manuscripts — and shipped them to Paris, where they entered the Bibliothèque nationale and were fully inventoried in 1985 (Ghali, Mahibou, Brenner, Inventaire de la Bibliothèque ʿumarienne de Ségou). The irony is a mechanism: this looted collection is now the single best-catalogued large sample of a nineteenth-century West African scholarly library anywhere, precisely because colonial capture moved it into a metropolitan institution with cataloguing labour, while its in-situ peers — the working libraries of Ségou, Hamdullahi, Nioro, Dinguiraye that were not captured — stayed uncounted in family hands or were dispersed. Description density is therefore inverted relative to survival in place: the captured and exiled collection is richly described, the collections that stayed home are dark. So the corpus we can actually read of the Umarian/Tijani sphere is dominated by the one fonds that was stolen. Prediction: in a union of the openly described West African Arabic manuscript collections, the BnF Bibliothèque umarienne de Ségou will by itself account for more item-level catalogued manuscripts of the pre-1900 Umarian and Tijani sphere than all in-situ Malian and Guinean collections of that sphere combined — over half of the described corpus sitting in the single looted fonds (primary clause: the captured collection holds the majority of described items of its sphere; the verdict follows it). Kill: the BnF's catalogued Bibliothèque umarienne de Ségou (Noureddine Ghali, Sidi Mohamed Mahibou, Louis Brenner, Inventaire de la Bibliothèque ʿumarienne de Ségou, CNRS 1985; BnF Département des Manuscrits, fonds Arabe), counted against the West African Arabic Manuscript Database (AMMS) and the SAVAMA-DCI and EAP in-situ inventories for the Umarian and Tijani sphere.

Novelty / leakage triage

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

The Ségou library's seizure by Archinard in 1890 and its cataloguing in the 1985 Inventaire umarienne are documented, and the irony that colonial removal produced the best-described West African scholarly library of its kind is a commonplace of the Umarian literature (Robinson; Brenner). But the primary clause is a comparative majority-share: that the single BnF fonds holds more item-level catalogued manuscripts of the pre-1900 Umarian/Tijani sphere than all in-situ Malian and Guinean collections of that sphere combined. No one has built the sphere-restricted union-and-diff of the Inventaire against the SAVAMA-DCI, EAP and AMMS in-situ inventories, so the over-half proportion is un-run. The nearest prior art describes the collection and its provenance richly but does not tabulate its dominance over the in-situ corpus.
