  We review the main results we have obtained in the area of high-energy
elastic hadron scattering and presented in this series of Workshops on Hadronic
Interactions. After an introduction to some basic experimental and theoretical
concepts, we survey the results reached by means of four approaches: analytic
models, model-independent analyses, eikonal models and nonperturbative QCD.
Some of the ongoing researches and future perspectives are also outlined.
