  We present an extensive catalog of 5405 early-type dwarf (dE) galaxies
located in the various environments, i.e., clusters, groups and fields, of the
local universe ($z$ $<$ 0.01). The dEs are selected through visual inspection
of the Legacy survey's $g$-$r$-$z$ combined tri-color images. The inspected
area, covering a total sky area of 7643 deg$^{2}$, encompasses two local
clusters, Virgo and Fornax, 265 groups, and the regions around 586 field
galaxies of $M_{K}$ $<$ $-$21 mag. The catalog aims to be one of the most
extensive and publicly accessible collections of data on dE, despite its
complex completeness limits that may not accurately represent its statistical
completeness. The strength of the catalog lies in the morphological
characteristics, including nucleated, tidal, and ultradiffuse dE. The two
clusters contribute nearly half (2437 out of 5405) dEs, and the 265 groups
contribute 2103 dEs. There are 864 dEs in 586 fields, i.e., ~1.47 dEs per
field. Using a standard definition commonly used in literature, we identify 100
ultra-diffuse galaxies (UDGs), which take ~2% of the dE population. We find
that 40% of our sample dEs harbor a central nucleus, and among the UDG
population, a majority, 79%, are nonnucleated. About 1.3 of dEs suffer from
ongoing tidal disturbance by nearby massive galaxies, and only 0.03% show the
sign of recent dwarf-dwarf mergers. The association between dEs and their
nearest bright neighbor galaxies suggests that dEs are more likely created
where their neighbors are non-star-forming ones.
