B physics at CDF

The CDF experiment at the Fermilab Tevatron has proven to be well suited for precision studies of b physics. Thanks to the excellent performance of the Tevatron Collider and the detector, CDF has accumulated very large data samples and roughly a decade of experience with b physics in pp-bar collisions. With the much higher luminosities expected for the Main Injector era, the next decade promises to be an even more fruitful period for CDF. Here we offer a brief overview of issues in hadron-collider b physics and a summary of CDF's accomplishments and future plans
