    "abstract": "A brief survey is presented of recently discovered hadrons, some of them\npresumably demonstrating a new kind of internal structure. This includes :\nspin-singlet quarkonium, mesons with unexpected mass or width, baryons with two\nheavy quarks, and pentaquark candidates. Flavour configurations with a\ncombination of light and heavy quarks appear as particularly promising.",
