Trans-Neptunian Objects

We are planning an update to 523.4 Planets of the solar system and would like feedback on the proposed new development. Because of the recent reclassification of Pluto as a dwarf planet by astronomers and the discovery of other Trans-Neptunian Objects (TNOs), the following development in Edition 22 is out of date:
        523.48    Trans-Uranian planets
        523.481        *Neptune
        523.482        *Pluto
*Add as instructed under 523.4

We propose to modify the schedule as follows:
        523.48  *Neptune
        523.49    Trans-Neptunian objects
        523.492        Kuiper belt objects
        523.4922            *Pluto
        523.494        Scattered disk objects
        523.497        Oort cloud objects
*Add as instructed under 523.4

The Decimal Classification Editorial Policy Committee (EPC) has approved the new development in principle, but requested that we seek user feedback before implementing the change.  Please either post your comments directly to this blog entry or direct your comments to dewey@loc.gov by February 15, 2008.

I always felt Pluto should be 523.49 anyway. I'm a LMA in an elementary school in Virginia so we don't use but 2 or 3 decimals anyway so 523.49 would work best for us.
