Mean-motion resonances in the Solar system
A curated collection of essential papers on mean-motion resonances in the asteroid belt, TNO, and beyond.

First discovery of the presence of three-body MMRs in the main belt
The manuscript reveals that there are not only two-body but also three-body MMRs in the main belt. The authors found several asteroids (e.g., 490 Veritas) trapped in 5J-2S-2 with Jupiter and Saturn. Three-body MMRs are much more populated in the main belt compared to the two-body because of the number of possible linear combinations of integers. Also, the paper introduces a method to identify a resonance, though some details could stay unknown (for the method I recommend reading a more focused paper).
