Alas, Babylon

"Alas, Babylon." Those fateful words heralded the end. When a nuclear holocaust ravages the United States, a thousand years of civilization are stripped away overnight, and tens of millions of people are killed instantly. But for one small town in Florida, miraculously spared, the struggle is just beginning, as men and women of all backgrounds join together to confront the darkness.

I believe that it is important to "real books" in your reference library. Just in case. I have just finished re-reading "Alas, Babylon" for the third time & each time I think it is better than the last. 
Initially my only shock was dealing with the racial epithets. But keeping in mind that this was written in 1959, I felt that the main family of color was treated as respectfully as possible considering the era. They were an integral part of the survival of the group that gathers.
Since the story is told from the perspective of only having a short time to gather items they believe will be helpful for the impending disaster, it shows the ingenuity of learning new skills and learning how to expand the resources they had on hand.  
Personally I highly recommend actually buying this book for our bookshelf.
It is worth every penny.

 Seriously, depending on what you think is a good possible scenario for a TEOTWAWKI, I would think you would want to also have a copy on hand.
