I'm trying to create a bibliography style that outputs a short summary (which I've put in the abstract field), followed by a separate longer blurb. I've used Abstract for the short blurb, and got that to appear at the end of the bibliography entry, but I've had no success putting the longer blurb into the Extra field and getting it to appear using .

Does anyone know if/how it is possible to use the Extra field in this way? Or if I put the longer blurb in Notes, can I get that to appear in the bibliography entry?

To explain, I'm working towards creating a style that will make it easier to create web pages for my institute's publications based on a Zotero entries. The web page set-up has an Intro text (short blurb) and a longer text (long blurb). For now I just want it to be easier to cut and paste, but in the long term I want to be able to create the pages automatically, hence it will be better if the short and long blurbs are in separate fields.

Thanks for all suggestions!
