Two main techniques employed have each come across difficulties which were largely unforseen at the outset.- deep imaging - search for Lyman alpha emission (blank sky and known QSO) Steidel et al. 1996, ApJ, 462, L17 (received: Dec. 1995) Spectroscopic Confirmation of a Population of Normal Star-forming Galaxies at Redshifts z> 3 (19 z>3 galaxies) Steidel et al. 1996, AJ, 112, 352 (received: Mar. 1996) Spectroscopy of Lyman Break Galaxies in the Hubble Deep Field
