The electronic properties of stacks of graphene layers are reviewed. The Landau levels, and the role of stacking disorder are considered. Electron-electron interactions are also analysed, and it is shown that, near the neutrality point, they can change significantly the ground state properties. The screening of external fields, and the charge distribution among the different planes, is determined by interaction effects and interlayer hopping, leading to Friedel-like oscillations.
