My solution - display them! What, you don't like the look of neon paint splattered book spines from the '80s? Me either.
I found these awesome leather-esque fabrics at my local craft store for around $8 a yard. I cut it to fit the spines and then taped to the inside like a dust jacket. Voila, interesting volumes on your bookshelf. (I also covered some random hardbacks to round out my bookshelf design. The yearbooks are on the far right).
Again, I'm working on better photo skills. This image is very washed out looking. Take my word that these look much better in person!
