Citation and Version Information¶

Each ETIS publication has a permanent identifier, a stable public record, an authoritative PDF edition, and a version history. This page explains how to cite, reference, and interpret ETIS publications.

Publication Identifiers¶

ETIS uses permanent identifiers that are never reused:

Series	Identifier pattern	Example
ETIS White Paper Series	`WP-###`	`WP-001`
ETIS Executive Brief Series	`EB-###`	`EB-001`
ETIS Education Paper Series	`COMP-WP-###`	`COMP-WP-001`

A revision normally retains the same identifier. A new identifier is assigned only when the work becomes a substantively different publication.

Authoritative Edition¶

The downloadable PDF is the authoritative publication edition. The website page serves as the canonical record for discovery, metadata, citation, version status, and related ETIS materials.

Word source files are working documents and are not authoritative public editions.

A complete citation should include:
