I need a list, as complete as possible, of real piano repertoire pieces.

The list should be organized according to technique and difficulty.

For example, pieces that use octaves -- simple to difficult.

Does anyone know where I can get my hands on this? I'm sure someone has created this before.

I want to be able to cover all areas of technique with literature. I want say five pieces at a time that will cover the major areas of piano technique. I can simply plug in a new piece that covers a certain technique when I'm finished with that piece.

I need this for myself and for my students.
