The morphological types of 5840 galaxies were classified by a visualinspection of color images using the Sloan Digital Sky Survey (SDSS) DataRelease 7 (DR7) to produce a morphology catalog of a representative sample oflocal galaxies with $z<0.01$. The sample galaxies are almost complete forgalaxies brighter than $r_{pet}=17.77$. Our classification system is basicallythe same as that of the Third Reference Catalog of Bright Galaxies with somesimplification for giant galaxies. On the other hand, we distinguish finefeatures of dwarf elliptical-like galaxies to classify 5 subtypes: dwarfellipticals (dE), blue-cored dwarf ellipticals (dE$_{bc}$), dwarf spheroidals(dSph), blue dwarf ellipticals (dE$_{blue}$), and dwarf lenticulars (dS0). Inaddition, we denote the presence of nucleation in dE, dSph, and dS0. Ellipticalgalaxies and lenticular galaxies contribute only $\sim1.5\%$ and $\sim4.9\%$ ofthe local galaxies, respectively, whereas spirals and irregulars contribute$\sim32.1\%$ and $\sim42.8\%$, respectively. The dE$_{blue}$ galaxies, whichare recently found populations of galaxies, contribute a significant fractionto the dwarf galaxies. There seems to be structural difference between dSph anddE galaxies. The dSph galaxies are fainter and bluer with shallower surfacebrightness gradient than dE galaxies. They also have lower fraction of galaxieswith small axis ratios ($b/a \lesssim 0.4$) than dE galaxies. The meanprojected distance to the nearest neighbor galaxy is $\sim260$kpc. About $1\%$of local galaxies have no neighbors with comparable luminosity within aprojected distance of 2Mpc.
