Hi Leanne,
Thanks so much for your detailed reply. I am using Endnote version X7 (not online).
Both bibliographies are an Endnote generated field and when I unformat the citations both bibliographies disappear and all citations are visible in curly brackets. The fact that they all look the same is what is particularly confusing
I’m not sure if this is a clue but in the Endnote library, most of the entries are in bold but some are not. I don’t think tis has any bearing on which ones appear in which biblioraphy though.
Thanks for the offer of support. Unless you have any additional things I can try I’ll get in touch with tech support as suggested.
Thanks!
