Description
TL;DR: A declassified administrative and technical manual showing how communications metadata was converted into structured traffic-analysis records.
About This Document
Issued by a U.S. signals-intelligence production organization in 1955, the TEXTA manual defines casebooks, temporary and permanent notations, extracts, indexes, reporting formats, and rules for maintaining traffic-analysis information. It includes examples and organizational conventions for communications-intelligence work across multiple target areas. The preserved file was declassified decades later.
Why Bitcoin People May Care
This is not a Bitcoin document. It shows the institutional machinery behind metadata analysis: the intelligence value comes from disciplined records of who communicates, when, how, and through which network structures. Bitcoin users face a modern peer-to-peer metadata problem, but the manual does not describe cryptocurrency surveillance or current defensive practice. It is a historical primary document.
