What to do now
The Limits of Offline First-Aid References
Build a local index
List the information your household or team cannot afford to lose, then identify where each authoritative copy lives.
Preserve source and date
Keep the original publisher, revision date, scope and limitations beside every saved reference.
Test access and recovery
Open the files without internet, restore a separate copy and record what failed before an emergency.
Practical limits
Offline references can become outdated and cannot replace current alerts, emergency services, licensed professionals, required equipment or sound judgment.
