  The mini-proceedings of the 17$^{\mathrm{th}}$ Meeting of the "Working Group
on Radiative Corrections and MonteCarlo Generators for Low Energies" held in
Frascati, 20$^{\mathrm{th}}$ - 21$^{\mathrm{st}}$ April, are presented. These
meetings, started in 2006, have as aim to bring together experimentalists and
theoreticians working in the fields of meson transition form factors, hadronic
contributions to the anomalous magnetic moment of the leptons, and the
effective fine structure constant. The development of MonteCarlo generators and
Radiative Corrections for precision $e^+e^-$ and $\tau$-lepton physics are also
covered, with emphasis on meson production. Heavy quark masses were covered as
well in this edition.
