ASTM Compass
ASTM Compass is the subscription digital library and workflow platform that delivers ASTM standards alongside third-party publisher content (AASHTO, API, BSI, etc.), books, journals, papers, and video standards. Compass supports version comparison (color-coded redlines), change alerts, annotations, attachments, sharing, and Compass Points metadata tagging. It is delivered as a subscription service to enterprises, libraries, and universities, and integrates with customer identity systems via SAML SSO, Shibboleth, OpenAthens, and IP-range authentication. There is no public REST API for the Compass content catalog; integration is identity-only.
