A Little OCD About My Bookshelf

A few years ago I started actually buying the books I read, rather than borrowing from friends or getting them from the library (okay, not all, but most).  I did this mainly because I have a goal to have a kick ass library in our future house someday (inspiration below).  Spare me on the Kindle speech, I don't want one, I like REAL books.
 

 

Over the past few years I've accumulated about 60 books, and yes, I like to keep them on display.  Right now they fill about 3 shelves on my bookshelf in the living room, and I have them organized by color.  CAhusband thinks this is an absurd way to organize books; however, after seeing it in a decor magazine (like the inspiration photo above) I decided to try it with our books, just to see how it looked.  Although it's a little cheesy, I like it, but here's where the OCD comes in.

 

• I have tons of red, blue, and black books... but only a few of the other colors.  I now ridiculously find myself searching for orange, green, and purple books at the bookstore, simply because of their color.  Obviously, I'm not that OCD and stop myself from actually purchasing them, but I definitely think about it for a significant amount of time.
• When I loan a book out to a friend I really miss it!  (If you're reading and have borrowed a book from me, this isn't a hint, keep it, this is my OCD we're discussing here).  I loaned The Help to the school secretary, and it's one of my very few yellow books.  I now nearly obsess over how my shelf looks "funny" without it there.
• Piper has eaten several of my books, that were once more spaced out through all 5 shelves (now they're only on the top 3, so she can't reach).  Although my books are some of my most prized possessions, I've chosen to deal with it; UNLESS, she ate a book that belongs to a series that I've collected!!!!  For example, I own all of the Emily Giffin books, and Piper ate Love the One You're With (the green one).  Now this was especially painful because I seriously take pride in having all of the books by an author, and it was one of my FEW green books!  Although I've read the book, I now find myself REALLY wanting to re-purchase it!  How ridiculous is that?? 
• While watching TV, CAhusband will find me staring at the bookshelf.  What am I doing?  I'm obsessing over if the shades of the books are organized correctly, like should I organize the shades of blue from light to dark, or dark to light?  Where should the aqua/turquoise books go? Where do black and white books fall into the rainbow spectrum?

After all of this obsession I'm starting to think I should maybe I should un-do the color coding!  What do you think?  Do you buy your books or utilize the library?  How do you organize your books?
