  The European Large Area ISO Survey (ELAIS) has surveyed 12 square degrees of
the sky at 15 and 90 microns, and subsets of this area at 6.75 and 175 microns,
using the Infrared Space Observatory (ISO). This project was the largest single
open time programme executed by ISO, taking 375 hours of data. A preliminary
catalogue of more than 1000 galaxies has been produced. In this talk we
describe the goals of the project, describe the follow-up programmes that are
in progress, and present some first scientific results including a provisional
number count analysis at 15 and 90 microns.
