Trusted Organizations and Sources
If a topic is safety-critical, time-sensitive, or system-specific, use the direct source page that owns the rule. The point is not to collect pretty homepages. The point is to reduce the odds of citing the wrong thing when the stakes are real 12.

How to use this page
Use the source that best matches the topic, then read the practical page in this handbook. The handbook should synthesize, not replace, the underlying guidance. For fast-moving topics, check the source date or the page’s current update status before treating the guidance as current 12.
Good habits
- Prefer official public-health or professional organizations.
- Check the date when guidance is especially time-sensitive.
- Use regional sources for car seats, leave, coverage, and child care rules.
- Prefer direct topic pages over organization homepages when both exist.
- Keep a local copy or bookmark of the exact page you cited if the topic is likely to change.
What not to do
Do not choose sources because they are the easiest to read. Choose them because they are authoritative, current, and actually responsible for the topic you are asking about. That keeps the handbook useful when the topic is safety-critical or when the rules differ by country 12.
