Ed is correct about most speaker manufacturers not taking this type of speaker placement into account. You can get this set-up to work, it is just that you will give up certain 'audiophile' things like soundstage and separation ... the sound will just be there. The walls of the bookshelf will present boundary issues, so the speakers will need to be towards the front of the shelf, so to speak. The enclosed nature of the bookshelf may provide some bass reinforcement. At its best, you will have speakers that sound pretty good, but will not deliver all that they are capable of delivering.
Most likely, you will be placing the speakers on their sides. It looks better, believe it or not, but you can also optimize the sound a bit by placing the speakers in such a way where the tweeters are to the outside ....

Stick with speakers that are front ported or sealed box design, though there are some rear ported speakers that have been designed to sound good next to rear walls. Obviously, stay away from any speakers that have curved sides.
I have tried a number of speakers in this set-up and my favorites are:
1. Energy RC 10
2. Rega R1
3. Omega Loudpeakers . These speakers are crossover-less and have only one speaker. They tend to sound best with tube amps.
