abstract: 'Results of a 4 year X-ray monitoring campaign of the Small Magellanic Cloud using the Rossi X-ray Timing Explorer ([[*RXTE*]{}]{}) are presented. This large dataset makes possible detailed investigation of a significant sample of SMC X-ray binaries. 8 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.'

The Survey
==========

A program of regular observations of the Small Magellanic Cloud (SMC) using the [*Rossi X-ray Timing Explorer*]{} (RXTE) has been underway since 1997, in conjunction with optical imaging and spectroscopic follow-up observations. New SMC pulsars discovered by [[*RXTE* ]{}]{}have been reported in a number of publications, and this work is intended to present the wealth of long-term data now accumulated for these sources. This paper reports the results of 4 years (November 1997 -
