The Large Area Telescope (LAT) on Fermi in three months produced a deeper and better resolved map of the gamma-ray sky than any previous space mission. We present here initial results for energies above 100 MeV for the 205 most significant (statistical significance greater than ~10sigma) gamma-ray sources in these data. These are the best characterized and best localized point-like (i.e., spatially unresolved) gamma-ray sources in the early mission data.galaxies activegamma rays observationspulsars generalsurveys10.1088/0067-0049/183/1/46http://adsabs.harvard.edu/abs/2009ApJS..183...46A2009ApJS..183...46A
