History

Why this record matters
A short description can identify a subject without explaining its stakes. For “Organisation of Islamic Cooperation”, the useful work is to connect “international organization” to the records capable of establishing context and consequence.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q47543. VIAF identifies the subject as 302216036. The Library of Congress control number is nb2012022645. 2 of 5 selected statements include explicit references; 3 carry qualifiers and 1 use preferred rank. The first chronological checks are 1969 and 2015.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
