You will hold in your hands the proceedings of the last conference ever on integral-?eld spectroscopy. So the daring statement that we, organizers, made at the end of an extremely interesting and busy week of conference in October 2005. Indeed, the quality and diversity of the contributions in this book indicated that integral-?eld spectroscopy had evolved into a mature technique. Future books would not be dedicated to the technique as such but to the science achieved with 3D-spectroscopy, that is a dedicated book after thisone, assemblingscienceresultsacrosssomany?elds, isunlikelytoappear...

Recently, improved observational capabilities have allowed the study of fainter and fainter extra-galactic planetary nebulae in galaxies well beyond the Milky Way. This book result from a workshop held at ESO headquarters in Garching in 2004, the first devoted to Extra-galactic Planetary Nebulae. A wide range of topics is covered, from stellar and nebular astrophysics to galactic dynamics and galaxy clusters, making this a reference of broad astrophysical interest.
