This symposium honors the contributions of Charlotte Moore Sitterly as a pioneer of spectroscopy, and astronomical spectroscopy in particular. The need for precise and accurate laboratory data in astrophysics has not diminished. Every time better spectrographs are built or new wavelength domains explored, we find critical information missing that is needed for analyses to derive abundances or to compare models of stars and planets to observations, in order to more fully understand the universe that we observe. IAU Symposium 371 encompassed nearly all the science themes that the IAU covers, from near to far in the universe, and at all wavelengths. But it concerned more than lab work in and of itself and brought together laboratory astrophysicists with the people who use that information, to learn about current advances and limitations, and future needs. A broad spectrum of the IAU's membership can benefit from these proceedings.
