Result. of a 4 yr X-ray monitoring campaign of the Small Magellanic Cloud using the Rossi X-ray Timing Explorer (RXTE) are presented. This large data set makes possible detailed investigation of a significant sample of SMC X-ray binaries. Eight new X-ray pulsars were discovered, and a total of 20 different systems were detected. Spectral and timing parameters were obtained for 18. In the case of 10 pulsars, repeated outbursts were observed, allowing determination of candidate orbital periods for these systems. We also discuss the spatial and pulse-period distributions of the SMC pulsars.
