About this list

This page lists every document the site cites: standards, statutes, regulations, publisher catalog pages and government works. Each entry gives the designation, title, edition and publisher, how the site holds the document, the month a purchased copy was acquired, and the pages that cite it.

A purchased standard is held under the publisher's license, bought from its publisher or an authorized seller. Its text is read to extract facts and is never reproduced on the site. Links point to the publisher's official catalog or sales page, never to a copy of the document.

Bibliography

Sources by class. How each cited document is held: licensed standards are purchased single-user copies; catalog, agency and government pages are public.

Sources by class: sources per row.
