[Cover illustration] Cover illustration: The hydrogen bonding in 5-hydroxy-6-methyl-2-pyridone, showing six sets of hydrogen-bonded dimers forming puckered rings, in which the O atom of each N-H...O interaction is also the acceptor in an O-H...O hydrogen bond involving the 5-hydroxy group as donor. See Parkin & Behrman [Acta Cryst. (2011), C67, o324-o328].
