Problem: I need to display a list (via Views) of field collection items from the child pages on a book's top level page.

Details
I have several books with the related child pages. The book top level page contains the details of an academic course (e.g. Neurobiology), the child pages present the detailed weekly structure of individual courses (Course 1: Synapse functions, Course 2: Glutamatergic synapses, Course 3: Receptor function, etc.). Each of the child pages also has a field collection consisting of bibliographic references (so Course 1 has Biblio 1, Biblio 2, Biblio 3, etc; Course 2 has Biblio 2, Biblio 4, Biblio 5, etc.). I would like to display automatically a list of Biblio items gleaned from the child pages on the book's top level page.

I have managed to get a list of ALL field collection (bibliography) items from all books via Views, but I am stuck with figuring out how to constrain the list based on a specific book top level page. How can I relate the book ID to the field collection item id via the child page?

Thank you for any suggestion!
