This effect should be strongest for the lowest-mass and lowest-luminosity galaxies. To study dwarf galaxies in extremely low density environments, we have compiled a deep catalogue of dwarf galaxies in the nearby Lynx-Cancer void. This void hosts some of the most metal-poor dwarfs known to date. It borders the Local Volume at negative supergalactic Z(SGZ) coordinates and has a size of more than 16Mpc. With a distance to its centre of only 18Mpc, it is close enough to allow a search for the faintest dwarfs. Within the void 75 dwarf (-11.9>MB>-18.0) and four subluminous (-18.0>MB>-18.4) galaxies have been identified. We present the parameters of the void galaxies and a detailed analysis of the completeness of the catalogue as a function of magnitude and surface brightness. File Summary:

Note (1): The velocity Vdist: * when marked by an asterisk (*) corresponds to D(Mpc)x73 where the photometric (TRGB, Cepheids) distance D(Mpc) is available; typical accuracy is ∼10%). * otherwise, this is VLG+Vpec, where Vpec∼300km/s is a correction for the peculiar velocity.
