Two Decades in the Life of EXO 2030+375

EXO 2030+375, a 42-s accreting pulsar in a 46-day orbit around a Be star, has undergone a detected outburst at nearly every periastron passage since 1991. It has been monitored with BATSE, RXTE, and Fermi/GBM. We will present preliminary results of long-term monitoring, including a long-term frequency history, long-term pulsed flux measurements, and available long ]term optical/ir monitoring results
