To guide research into formation scenarios for giant planets, I present a catalogue of 199,391 sources with candidate protoplanetary disks. These candidates are identified through an iterative color selection process in a 5,460-dimensional color-color space. As part of this process, photometry and SIMBAD classifications are aggregated from multiple large surveys, collectively covering 14 optical and infrared bands from 0.35 – 22 microns. An estimated false positive rate of 36.1% makes this catalogue a suitably sturdy foundation for a wide range of subsequent studies. After a discussion of the context surrounding this research, the forthcoming journal article describing this catalogue is reprinted in its entirety, and commentary is offered on the results.
