Dwarf galaxies offer a valuable insight into the physical processes that govern galaxy formation and evolution at high redshift. These elusive stellar systems are helping astronomers to find answers to some of the most burning questions in extragalactic astronomy. Present-day dwarf galaxies, the easily studied survivors of the primordial galaxy population, are important targets for research in the quest to provide local benchmarks for cosmological studies, in particular theories of structure formation. The proceedings of IAUC198 offer an exciting multidisciplinary collection of research results. The interpretation of the faint blue galaxy excess; the mismatch of the observed dwarf galaxy numbers with popular cosmological model predictions; and the puzzling diversity of star-formation histories among Local Group dwarf elliptical galaxies, are amongst the topical questions covered. Dwarf galaxy specialists and cosmologists map out strategies and outline a framework for progress on important issues related to near-field cosmology with dwarf elliptical galaxies.

Cosmology has not been the subject matter of a Saas-Fee Advanced Course since 1978. That occasion was the memorable course entitled Observational Cosmologyy with lecturers J.E. Gunn, M.S. Longair, and M.J. Rees. A new course on cosmology seemed overdue, and we subsequently planned and or­ ganized, with the endorsement of the Swiss Society of Astrophysics and As­ tronomy, the present, 23"^^ Saas-Fee Advanced Course. Probing (drilling) the Universe to greatest depths, in terms of diffuse radiation and discrete objects, with all consequences for our understanding of cosmic evolution, was meant to be the unifying aspect of this course. Hence the title The Deep Universe. We are very happy to have won such competent and brilliant scientists as lecturers. Malcolm Longair - Saas-Fee lecturer for the second time! - lectured on cosmological background radiation ("The Physics of Background Radia­ tion"); Richard Kron on observations of extremely distant galaxies ("Evo­ lution in the Galaxy Population"); while the Grand Master of Cosmology, Allan Sandage, provided the fundaments of it all, also in a historical sense ("Practical Cosmology: Inventing the Past"). The course took place from 29 March to 3 April, 1993, in Les Diablerets, with around 90 participants. The format was as usual, every lecturer giving 9 or 10 lectures of 45 minutes.
