Scalar-tensor cosmology with R^{-1} curvature correction by Noether   Symmetry
  We discuss scalar-tensor cosmology with an extra $R^{-1}$ correction by the Noether Symmetry Approach. The existence of such a symmetry selects the forms of the coupling $\omega(\phi)$, of the potential $V(\phi)$ and allows to obtain physically interesting exact cosmological solutions.
