The status of the Brookhaven-based muon (g - 2) experiment, E821 is presented, along with possibilities for future improvements. Four of the five data sets are now published, which have produced a value for αμ+ with a relative precision of ±0.7 parts per million. The final data collected using μ- is being analyzed, and the result is expected early in 2004.
