Warning: This library crashes on render in Blender 2.70. The Library was built in Blender 2.67. I will look into updating it as soon as possible. for now, appending the materials to your scene still works. Thanks.
Categorized OSL & Cycles node materials. All materials are as fake user, each sphere has multiple materials. There's a good test scene Scene_Objects_Cycles in the .blend The materials in the library have been set up to work on these objects. The scale of the objects is standard blender add object scale. All materials have been named for easier appending.
