I’m working on a project for a book that is a collection of essays.

Each one needs at its end a list of references.

Of course I’ve started from here

But how can I force context to take into account only a portion of text for generating bibliographic references and for inserting a block of references after a section?

(To collect all refs in a single bib file or to have split bib files is not an issue)

Thanks a lot, 

Best
