Thanks for the rapid response. If I’m understanding correctly it’s possible to use two output style but only if ultimately converting the field codes in the first set to, say plain text, and then after removing temporary delimiters of the second set, selecting the second output style, and updating the citations and bibliography. After testing the question was answered but I ended up with a document where some of the citations and references were plain text while others still had field codes. So I’m assuming for a working document it would be difficult to use two output styles and make additional changes (e.g., adding or removing citations, changing citation order etc.,) to both sets of text without losing the benefit of EndNote updating the bibliography of the first set of text. This would therefore work best if all text in the document was final - is that a correct assumption?
