I know this one has been asked before, but I can't recall what the answer was, and can't find the answer in the archive. I need to use more than one .bib file with my thesis, and so need to include them both in the bibtex reference box. At present one of these is a @strings file, and is needed for the bib file. I have tried just specifying both files (including and excluding path names) in the dialog box, seperated first by a comma (didnt work) second by a semicolon (didnt work). Can anyone help with this? Cheers Tony
