      Abstract:

      The following sections are included:

      • Introduction: which sample for which science goal?

        • General rules to optimize the scientific returns from a survey of distant galaxies

      • General rules for estimating magnitudes

        • Monochromatic and integrated magnitudes

        • Photometric systems

        • Total magnitudes and proxies

        • Absolute magnitudes

      • Pre-selection of a sample prior to redshift measurement

        • Photometric catalogs

        • Statistics: which size for a redshift survey?

        • Cosmological variance

        • Depth of the photometry and selection effects related to surface-brightness

        • Other selection effects: Malmquist bias, Eddington bias, and lensing effects

        • K-correction and choice of the selecting magnitude

      • Redshift surveys

        • Redshift measurements and spectroscopic selection effects

        • Determination of the LF, uncertainties and completeness tests

        • Examples of surveys (CFRS, DEEP2, VVDS, zCOSMOS, and WIGGLEZ)

      • Photometric redshifts

      • Selection of very distant galaxies at z ≫ 1

        • Lyman break galaxies (LBGs)

        • Balmer and 400nm break drop-out galaxies

        • Lyα emitters (LAEs)

        • Indirect probes: damped Lyα systems (DLAs) and gamma ray burst hosts

        • Dust-enshrouded galaxies

        • Towards an overview of the high-z galaxy population and a fair determination of the LFs

      • Relating distant and nearby galaxies
