Wide field imaging and spectroscopic surveys of the M31 system have
revealed a complex web of substructure surrounding the classical visible
galaxy, including: giant stellar streams; extended disk-like rotating
components; unusual classes of stellar clusters; many new satellite
galaxies; and even significant tidal streams emanating from M33 and NGC147. In this talk I will review some of the recent work on surveys in these systems and in particular discuss the latest results obtained from
ground-based and space-based imaging and spectroscopic data.
