How this entry is kept current

  • Citation status: carried from drafting; a source check is in the monthly scan queue.
  • Watched by: manual catalogue check each scan.
  • Automated scan: no public page to watch; checked by hand in the monthly review.

Every source is re-checked monthly and the result is published in the scan log. A change that alters what a document should say raises a revision, and past buyers of that document are told.
