Books on my shelf?

The book theme is all over today. Brigid, Murphy's Law, and North have all done it! I decided to follow suit. I kind of have to being the book girl. Granted my collection is not as wide ranging or as vast as some listed. I am a fiction junkie. I am also 29 and prone to moving regularly so I have to purge books a bit regularly. It makes me sad. At our last move i cried over the boxes of books I donated. *sniff sniff* I digress, my current collection has a lot of Louis L'amour. Husband is a fan but I sneak them when he isn't looking. I also love Clive Cussler and Dan Brown. The Adventure type action books. Faye and Jonathan Kellerman are great. I love paranormals so I have Laurell K Hamilton, Kim Harrison, Kelley Armstrong to name a few. Romance is also a love of course so Nora Roberts, Johanna Lindsey, Stephanie Laurens, Catherine Coulter both romance and FBI, Julie Garwood. I have a ton of favorite writers and know I am missing a bunch of them but honestly I have so many I am just listing what pops into my head. When we moved in here I had 12 boxes full. Hubby actually drove my books down himself rather than have the movers take them simply because of the weight. I have added quite a bit since then though now I have my Nook Color ereader and I try to put books on it rather than buying the bound versions in an effort to save space, hehehe. Poor husband wants to throttle me. My book cases are stacked to the gills 3 rows deep and up. Makes for heavy book cases! ;)

I am looking to now expand my collection into books we will need in a SHTF scenario. Medical info, food, living off grid, guns, things like that. If you guys know of good refrence books that I should have in a hardcopy form for a TEOTWAWKI life I would be very appreciative!
