This review provides an updated census of dwarf galaxies in the Local Group (LG) based on recent distance and radial velocity determinations. It discusses detailed properties of these galaxies, including integrated photometric parameters, optical structures, interstellar medium (ISM) content and distribution, heavy-element abundances, complex star-formation histories, internal kinematics, and interactions with other galaxies. The author presents extensive observational data tables to summarize what is known and unknown about these nearby dwarfs. The review highlights the importance of LG dwarfs in studying galaxy evolution, dark matter, and stellar populations. It also addresses the relationship between dwarf irregular (dIrr) and dwarf spheroidal/dwarf elliptical (dSph/dE) galaxies, the role of low-luminosity dwarfs in dark matter studies, and the complexity of their star-formation and chemical enrichment histories. The LG dwarfs' substructure and their structural properties are also discussed, along with the ISM characteristics such as HI content, dust, molecular gas, and HII regions. The review concludes by discussing the puzzles and challenges in understanding the LG dwarfs, particularly the lack of gas in some dSph galaxies despite ongoing star formation.This review provides an updated census of dwarf galaxies in the Local Group (LG) based on recent distance and radial velocity determinations.
