Selection effects in high-redshift submillimeter surveys and pointed   observations
  The results of the first generation of submillimeter-wave surveys have been published. The opening of this new window on the distant Universe has added considerably to our understanding of the galaxy formation process, by revealing a numerous population of very luminous distant galaxies. Most would have been very difficult to identify using other methods. The potential importance of selection effects, especially those connected with the spectral energy distributions of the detected galaxies, for the interpretation of the results are highlighted.
