Reddit mentions of Metal Gear Solid: Guns of the Patriot (1)

Sure thing!

• Metal Gear Solid - I am almost finished with this book. It is very detailed about everything, I highly recommend it.
  
  
• Metal Gear Solid 2: Sons of Liberty - I will be reading it shortly.
  
  
• Metal Gear Solid: Guns of the Patriots - Different author, but I am still excited to read it.
  
  
• Metal Gear Solid Omnibus - Graphic novel, I enjoyed it.
  
  
• The Complete Metal Gear Solid: Sons of Liberty - Another graphic novel, I am going to start it before I read the 2nd book.
  
  
  Unfortunately there is nothing for Snake Eater :-/

There are two Raymond Benson novels (MGS1, MGS2) then there's the one by Project Itoh for MGS4 (which I heard is really good).

There's also an artbook by Ashley Wood. Then there is the Metal Gear Solid Omnibus which is the comic series of MGS1 and MGS2 by a few writers with Ashley Wood's art. There's also the Deluxe Collection but it's pricey and I'm not exactly sure what makes it different from the Omnibus.

I think any Metal Gear Solid fan who doesn't own these would definitely appreciate them. I know I would.

There IS a novelization of MGS4. I suggest you give it a read.
