I investigate the theoretical uncertainties on the predictions for the longitudinal structure function. I compare the predictions using fixed-order perturbative QCD, higher twist corrections, small-x resummations and the dipole picture. I compare the various predictions to the recent HERA measurements and examine how the data still to be analysed may discriminate between the approaches.
