About this index
Dataset and reviewed rules
Tier 1: derived from the published letters index, the reviewed correspondent groups and the reviewed place list by the rules below — no inference, no model. Post-fold (sitting 2026-09-05): 169 reviewed correspondent groups; 2090 printed forms remain groups of one below the review floor, disclosed. Corpus version 5db27b8755bd; 170 records. Weighting constants: PROVISIONAL — the EC sitting's constants (2026-08-30) reused pending the Douglass correspondence sitting; changed only by a sitting. raw count everywhere — the count is the fact; ordering is presentation.
Identities: 172 of the 2,262 names in this layer are reviewed groupings. A name marked “as printed” is a form no ruling has reached — it may be one person, several, or part of another identity; an unmarked name is a reviewed identity.
Names and terms in the same records
Rule: vocabulary term (aliases OR-folded) × correspondent, FOLDER-level co-occurrence: the term's whole-word hit on a folder text × the person's letters in that folder — never letter-level (letter boundaries are not delimited beyond the anchors)
Order: distinctive first (lift) — records * N / (deg_term * deg_person); N = total fts records; degrees = graph_term_records / graph_person_records counts; support floor 5.

Rule: letters carrying both parties (the boundary sentence), grouped by the unordered pair of correspondent groups; see the builder A correspondence is counted only where both a sender and a recipient were read from the letter itself; letters with one party read are in no edge.
Correspondence weighting: Shared letters divided by the smaller of the two correspondents' totals of letters sent and received. Support floor 5. provisional; the EC alongside floor reused as the correspondence floor.
SELECT id FROM letters WHERE (sender_group = :person_a AND recipient_group = :person_b) OR (sender_group = :person_b AND recipient_group = :person_a) ORDER BY year, idHow these results are ranked
Distinctiveness (lift) compares how often a term and a name share records with the frequency expected from their separate record totals. It is not evidence of personal interest or influence.

Shared letters divided by the smaller of the two correspondents' totals of letters sent and received. This is the overlap coefficient, shown as a percentage.
