In our previous house the bookcases we had in our family room changed a lot.  They were the perfect place for me to create all kinds of different vignettes.  At one point our kitchen/family room and breakfast area were decorated with more of a Farmhouse style.  I thought we'd do a walk down memory lane to see how these bookcases changed all the time.
Our entertainment center is a piece we've had for years and years, it has fabulous storage and works well for us.  Big enough for a 32" tv and in a small room that is fine.  Plenty of storage for all the other electronics and movies.  I also use this to store napkins in one drawer and my chargers in one of the side cupboards.  That's perfect since it is part of the kitchen/breakfast/familyroom space.
Since this area of the house is done with a little more farmhouse decor than the living/dining areas, I keep the decor really casual.

This is the only picture I could find to show how the bookcases looked before I added beadboard to the backs several years ago.   Really dark and dreary.

One sheet of beadboard was perfect.  I just cut it to size and pushed it into the back.  It isn't glued, so if I change my mind down the road I can change it.

Major difference.  Wow, this piece came to life.

Now they really show off all of my "stuff".

Here are a few different ways I've had the shelves styled.  You can find some really great books at Goodwill, Salva...
