  We report results from a Spitzer GO-1 program of IRS spectroscopy of a large
sample of Luminous Infrared Galaxies and quasars selected from the European
Large Area ISO Survey (ELAIS) which have a wide multiwavelength coverage,
including ISOCAM, ISOPHOT, IRAC and MIPS (from SWIRE), and optical photometry.
We present the sample selection and results from the IRS spectroscopy.
