A brief overview is given of what we know of the baryon and meson spectra,
with a focus on what are the key internal degrees of freedom and how these
relate to strong coupling QCD. The challenges, experimental, theoretical and
phenomenological, for the future are outlined, with particular reference to a
program at Jefferson Lab to extract hadronic states in which glue unambiguously
contributes to their quantum numbers.Comment: 10 pages, 5 figures. Invited talk at the Eleventh Conference on the
Intersections of Particle and Nuclear Physics (CIPANP 2012), St Petersburg,
Florida. May29-June 3, 201
