  Since its identification as the Galactic Center, the radio source Sagittarius
A has been a target of intense research. Due to the high density of sources in
the Galactic Center and differing observing techniques, the nomenclature of
sources in this region has changed over the years, with sources having several
names, as well as the same names being used for different sources. We review
this historical evolution in the context of current and previous scientific
discussions, and outline how, why and when some of the commonly accepted names
of Galactic Center sources were established.
