This review presents an overview of the remarkable progress in the field of heavy-quark exotic hadrons over the past 15 years. It seeks to be pedagogical rather than exhaustive, summarizing both the progress and specific results of experimental discoveries, and the variety of theoretical approaches designed to explain these new states.

• Scattering processes and resonances from lattice QCD (2017, background): “Many of these, known colloquially as the “X,Y,Z ” states, have been found in the heavy quark sector (see (Chen et al., 2016; Lebed et al., 2017; Liu, 2014) for recent reviews on the topic), and a complete understanding of them remains elusive, with piecemeal proposals ranging from tetraquark…”
• Physics case for an LHCb Upgrade II - Opportunities in flavour physics, and beyond, in the HL-LHC era (2018, background): “Many states appear near the meson-antimeson (also meson-baryon) thresholds giving raise to molecular interpretations [461–463], or models involving hadron rescattering (cusps or triangle singularities) [464,465].”
• Hadronic molecules (2017, methodology): “For the experimental status and phenomenological models of other exotic candidates, we refer to several recent reviews (Brambilla et al., 2014; Chen et al., 2016a; Eichten et al., 2008; Esposito et al., 2015b, 2016b; Lebed et al., 2017; Richard, 2016; Swanson, 2006) and references therein.”
• Nonstandard heavy mesons and baryons: Experimental evidence (2017, background): “For this we refer the reader to three recent and comprehensive discussions of these issues by experts who have somewhat different viewpoints (118; 119; 360).”
