  Growing evidence for the existence of two classes of ellipticals calls for a
comparison of the properties of their globular cluster systems. I compiled
information on the properties of over 50 globular cluster systems of faint and
bright early-type galaxies, and investigated them in the light of the
properties of the parent galaxies. The properties of globular cluster systems
appear to separate into two classes rather than to follow continuous relations
with their host galaxy properties. Globular cluster systems in faint, disky
early-type galaxies with unresolved cores appear essentially unperturbed and
show no clear signs of a merger past, while systems in bright, boxy ellipticals
with resolved cores show all signs expected after a merger event. The globular
cluster systems are therefore compatible with the idea that major merger events
could be a cause for the dichotomy of early-type galaxies.
