I believe it depends on what bibliography style you're using. For dcu, at least, you can change "and" by adding the following to your preamble:
\renewcommand{\harvardand}{i} However, for "et al." and "in" (used for articles in collections) you would need to edit the style file. Note that "et al." is Latin, not English, so depending on the conventions used in Croatian you may not need to change it. (In English you occasionally see "and others" used in citations, but it is quite rare.) All the above is about natbib. I don't know anything about biblatex or biber. > -----Original Message----- > From: lyx-users@lists.lyx.org [mailto:lyx-users@lists.lyx.org] On Behalf Of > Goran Kardum > Sent: 18 September 2014 12:25 PM > To: lyx-users@lists.lyx.org > Subject: Lyx and references > > Hi, > I looked at introduction about Bibliographies and Bibtex in LyX using JabRef . > During last several months I try to write manuals for students and also the > book in Lyx.
