Color matching tables are available from ONYX if you are using their software. I do believe they are licensed by Pantone.
Pantone also publishes color guides (and Pantone Connect software for integration with Adobe Creative Cloud).
Pantone thinks very highly of their products. The cost may be considered high by some, but essential to others. Up to a few years ago Adobe would include Pantone color palettes in their software. They no longer do, and now you must buy a license from Pantone. I recommend their products if Pantone color matching is part of your workflow. Any digital copy will have significant color shifts (highly dependent on monitor and printer calibration) and be useful for only the most casual reference.
