Dwarf galaxies are central to theories of galaxy formation, contributing directly to knowledge on: the distribution and nature of dark matter; the processes of star formation; and the origin and growth of large-scale structure. Extremely low-luminosity dwarfs are only detectable at very short distances, within or near the Local Group, so very few are known. The first part (southern hemisphere) of an all-sky survey to discover more has resulted in one certain and one borderline new Local Group dwarf, plus a number of more distant dwarfs and low surface brightness galaxies. Extending this survey to the northern hemisphere, we have produced a list of approximately one hundred dwarf galaxy candidates. We propose to continue (and, if possible, complete) follow-up imaging of these to determine their nature.
