I want to build a PE library

I like having physical products in my shelf. I need y'all to help me compile a list of products.

I already own this book: http://www.amazon.com/Exercising-Penis-Prized-Healthier-Enlargement/dp/1434826317

A logical addition would be DLD's MoS DVD.

Now, what more can you think of?

Much obliged...
