Libertarianism is not anarchism, nor does it ever purport to be. In fact, libertarianism holds that a government should be in place, and that its job is to protect the rights (defined by libertarianism--most often, the Bill of Rights is pointed to) of its citizens.

Libertarians do overlap quite a bit with anarcho-capatilism and randism. You might not define libertarianism that way, but many do. The best you might say is something like, 'libertarianism, as espoused by [X], hold that a government should be in place.' As a counter example, I can easily find self-identified libertarians who are anarchists.
