Blender object libraries?

I am curious.
First, are their any large libraries for downloading pre-made Blender meshes? I know that Blender can import .dxf files, but I haven’t seen anyone really producing libraries specifically for Blender models.

Poser, Autocad, 3D Studio all have such libraries. Why not Blender?

Would these be something people would be interested in, either as contributors or users?

I have two objects available to anybody at
and .
There purely blenderian objects and I leave them in a parametric state so they can be easily modified.

I have lots more but no time to code the html. Some accompanying tutorials would be almost necessary for newbies.

I have some models that I have made and willing to share. Where do I send them?
