The case studies are seventeen books by Bart Moeyaert and La Belle Sauvage by Philip Pullman. The analysis of speech distribution, topic modelling, syntactic parsing, and lexical analysis with digital tools adds information about implicit age norms that can support and inspire narrative analyses with close reading.
