The DR3 Quasar Catalog from Schneider et al.
NOTE: This is a derived science table that may not be loaded for
every data release. It is scheduled to be reloaded for DR5.

This is a table containing all the quasars identified in the SDSS data. It is a derived table that is usually published after the main SDSS data is released. The paper describing the contents of this table is usually found in the Expert Background page of the SkyServer SDSS section (Schneider et al. 2005).
