CDF has performed a number of studies involving the production and spectroscopy of B mesons. Among these studies are the first direct observation of the Bc, and the first observation of both narrow states of the Bs**. In addition, measurements are made of the B** masses and widths and the best limit on the production of Eta_b is set.Proceedings of the EPS talk given on HEP 2007 in ManchesterHigh Energy Physics - Experimenttext
