Query: Globular cluster systems of early-type galaxies - do we understand them?   I review recent and less recent work on globular cluster systems in
early-type galaxies. Explaining their properties and possible assembly
scenarios, touches on a variety of astrophysical topics from cluster formation
itself to galaxy formation and evolution and even details of observational
techniques. The spectacular cluster systems of central galaxies in galaxy
clusters may owe their richness to a plethora of less spectacular galaxies and
their star formation processes. It seems that dwarf galaxies occupy a
particularly important role.
