Compiling a bibliography from several chapters

PS  Another option is to use “master documents” (but I don’t use them, so am not sure if there are still problems with that – the speaker in the 2nd video strongly recommends not to).  But here are instructions if you want to try it. – remember you still want to unformat the citations before combining – and you want to make sure you have all the records available in your library before doing so.
