At age 13, my Animorphs books stood proudly on those shelves. A few years later, Sweet Valley books joined the ranks. Soon, hefty Harry Potter hardcovers came along. Then school required classics hopped on. In the dorms, my bookshelf couldn't come with me, but a year later when moving into my first apartment, I dragged it from home to Irvine. I put CDs (lol Yellowcard) and various framed photographs on the shelves then. A year later, I moved into a different apartment and the bookshelf graced the area between my bedroom and the bathroom. I started owning DVDs at this point and those took the top shelf with old textbooks falling below. After college, I had no room for my bookshelf so it went home for a few years where my mother stole it for her room and put weird finance books on it.
Since moving back home in December, my first duty was to reclaim my bookshelf for my room. Finance books were dropped to the floor and good ol' Robin and I were reunited. Filling up bookshelves is always my favorite part of unpacking and it's the favorite thing in my room (sorry TV, sorry bed!). Every time my glance falls upon it, I smile because it embodies me. Sure it's a mess and it's overcrowded and my picture doesn't even show the bottom shelf (it's full of cookbooks) or the top (Harry Potter books and Drew Brees); nonetheless, I love it.

Stonewall is hiding on this bookshelf. I sort of think of it as Where's Waldo, but Where's Stonewall? If you can't find him in under 5 seconds, you should probably have your eyes checked.
My video game collection takes up the top shelf. The second shelf has two of my favorite cookbooks -- Mad Hungry and new classic family dinners -- I keep at eye level (I have to stoop down to the bottom shelf for the rest of my collection). Random books I own clutter the rest of that shelf as well as the one below it. The OC complete DVD collection sits hiding behind a makeup bags. DVDs (House, Gilmore Girls, Family Guy, Desperate Housewives -- I'm trying to sell the last two!) make up a majority of the fourth shelf along with a stack of manga I'm trying to sell on Glyde.com. The last visible shelf has my beloved collection of Everyday Food magazines, my BluRay collection and my DS games.
In retrospect, maybe this isn't fully indicative of ME, I have way more stuff in my room and plenty of things I hold near and dear aren't on these shelves, but I like to think of it as a snapshot of what makes me me.
PS: I've been in my room watching House, M.D. all day. I have a slight case of room fever.
