I liked JoJo's idea
Handbook to Practical Disaster Preparedness for the Family
by Dr. Arthur T Bradley
this is a plainly written well laid out book covering most major disasters and what to do about them.
each subject is set up in the same manner and it is easy to find information.
I liked the kindle book so much i bought a paper copy for my library.
it covers everything from the typical winter or summer storms to rarer and higher impact events.
it is practical and pragmatic. it is an excellent starter book and a good reference for rounding out your existing preps.
