[en] The status of the theoretical and experimental study of higher twist contributions to the nucleon structure functions is reviewed. After noting the dangers of combining experiments with widely different < Q2> and targets, emphasis is placed on those results coming from a single experiment. The values of ß, the twist-2 scale factor, and h4, the coefficient of x/Q2(1-x), are restricted by: ß <0.44 GeV and -0.2 < h4<0.5 GeV2
