We performed two surveys at the Calar Alto Observatory to identify low luminosity galaxies (LLG) in 4 fields towards nearby voids. While the central parts of the voids remain empty, we found about 20 very isolated (nearest neighbour distances of DNN ≥ 4Mpc) galaxies along the rims of some (but not all) voids (Hopp et al. 1995, Hopp & Kuhn 1995, Kuhn et al. 1996, Popescu et al. 1996). Many of them are dwarfs, a few are giants. CCD surface photometry revealed normal properties (Vennik et al. 1996), HI-observations show a tendency that the isolated dwarfs are overabundant in neutral gas compared to sheet and cluster galaxies of the same luminosity (Huchtmeier et al. 1996).
