   First Look Survey: Visual data from the Sloan Digital Sky
   Survey, in preparation.

The Sloan Digital Sky Survey imaged 16 square degrees of sky that includes
the Spitzer First Look Survey region, and released these data as part of their
Early Release Observations in June, 2001.
This dataset includes u',g',r',i',z' images and spectra.

Michael Blanton, Douglas Finkbeiner, David W. Hogg, Nikhil Padmanabhan, 
and David J. Schlegel have assembled all the SDSS images of the extragalactic 
First Look Survey field into four giant mosaics in each of five visual bands.
In addition, lower resolution mosaics of the entire field have
been created and spectra from the region are provided. JPG files of
the mosaics are also provided.
