How to use a source
- Confirm that it applies to your situation and contract.
- Record its title, URL, edition, and the date you checked it.
- Separate a source statement from your own assumption or worked example.
- Return to the current source when a decision, submission, or claim depends on it.
Each article links the specific material behind its factual context. Examples and worksheets are original educational aids, not official forms or government determinations.
