How to read the source list
Each guide lists the sources supporting its most important factual statements. We favor official agencies, licensing authorities, public programs, standards, and manufacturer instructions appropriate to the exact context.
The scope note explains what a source can support and where it stops. For a provider, property, vehicle, patient, or facility decision, verify the current record directly.
