An improved understanding of the connections between ultra-compact dwarfs, star clusters, and galactic nuclei requires a more complete and unbiased inventory of compact stellar systems in the nearby universe. We are conducting a systematic search through public archival data, including from both the Sloan Digital Sky Survey and the Hubble Space Telescope, for compact stellar systems around nearby galaxies. We present initial results, including the discovery of the new densest known galaxy, the densest star cluster, and a compact elliptical galaxy caught in the act of formation.
