Here, we focus on internal kinematics of nine GGCs, obtained from space-based imaging over time baselines of >9yr. We exploit multiple avenues to assess the dynamical state of the target GGCs, constructing radial profiles of projected stellar density, proper motion dispersion, and anisotropy. We posit that two-thirds (6/9) of our target GGCs are in an advanced dynamical state, and are close to (or have recently undergone) core-collapse, supported by at least two lines of evidence. First, we find relatively steep proper motion dispersion profiles, in accord with literature values for core-collapsed GGCs. Second, we find that our sample is, in the mean, isotropic even out to their half-light radii, although one of our target clusters (NGC6380) is tangentially anisotropic at >1{sigma} beyond its half-light radius, in accord with theoretical predictions for clusters evolving in strong tidal fields. Our proper motion dispersion and anisotropy profiles are made publicly available.2021AJ....161...41Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/41CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)VII/195 : Globular Clusters in the Milky Way (Harris, 1996)VII/202 : Globular Clusters in the Milky Way (Harris, 1997)J/AJ/109/218 : Catalogue of globular cluster profiles (Trager+ 1995)J/ApJS/161/304 : Star clusters in Milky Way & satellites (McLaughlin+, 2005)J/AJ/132/447 : Surface Brightness 38 Gal.
