In a previous work (Costa-Carreras 2016c
: “La planificació de corpus sobre el català: bibliografia classificada i comentada”) I reviewed the research on Catalan normative grammar systematically. The present paper aims at updating this information, but previously it focuses on the concept of research into normative grammar by analysing what objects, objectives, theoretical frameworks, methodologies, infrastructure and actors need to be involved. So in the first part the concept of research into normative grammar is analysed, and in the second part an update of the bibliography on research in Catalan normative grammar is provided.
