Pope Benedict XVI Bibliography

I’ve been searching and searching and was hoping that the collective knowledge on this forum might be able to help me.

For a research project, I’m seeking a comprehensive bibliography of the writings of Pope Benedict XVI, from his dissertation right on up through his time as a Cardinal and today. I’m having trouble locating one online, and was wondering if anyone knew of something I’m missing, in print or on the WWW.

Thanks in advance for your help!
