We extract the power corrections to the ''scaling'' proton structure function F{sub 2}(x,Q{sup 2}) by using QCD moments obtained from the world's inclusive lepton-proton scattering data. As opposed to previous analyses, we take particular account of data at large Bjorken x(x > 0.75) which are dominated by nucleon resonances and which make up most of the structure function at low Q{sup 2}(Q{sup 2}<=4 GeV{sup 2}). We discuss possible improvements on the determination of the magnitude of the higher twist coefficients that could be obtained from a new set of measurements of the nucleon structure functions at large x and moderate Q{sup 2}.
