Galactic centres are exciting as well as excited places. Their study is pushing atthe limits of technology, with high spatial resolution and wide wavelength cov-erage essential for progress. This conference volume follows the traditional IAUSymposium format, with long articles reviewing progress, and 2-page original con-tributions. Most of the short papers are too short to convey much. A few howeverfascinate: the story by Miyoshi of the near-discovery of the megamaser evidencefor a massive black hole in NGC4258 in 1992, 3 years before its actual discovery,illustrates just how close to the limits of technology, and available efforts, are majordiscoveries. Sakamoto et al. present elegant results showing that dense nuclearconcentrations of molecular gas are common.
