I'm trying to get citations rendered like this: (Bunks et al. 2001; Alex 1999). Please mind there is no comma after author's name.

I already tried natbib, authordate1-4 packes but with no success. In many cases there is a comma between the author and the date.

  • With Natbib activated, and the plainnat style, try adding \setcitestyle{aysep={ }} to the preamble (Document --> Settings --> LaTeX preamble.) – Torbjørn T. Jun 10 '14 at 20:22
  • It works, great, thank you! But what about multiple references citation where each reference has a page. In Lyx I get this as a result: (Bunks et al. 2001; Alex 1999, page 22) But sometimes, I want have for each reference a page: (Bunks et al. 2001, page 50; Alex 1999, page 22) I've found some solutions, but I do not know how to apply them in Lyx: tex.stackexchange.com/questions/166097/… latex-community.org/forum/viewtopic.php?f=31&t=2840 – BenTreeser Jun 11 '14 at 17:12
  • If you're using the natbib package, you use the command (\citealt{bunks01,alex99}); here, bunks01 and alex99 would be the keys to the respective entries. – Mico Jun 11 '14 at 18:54

If you're using the natbib package (as would appear to be the case), you could use \citealt instead of the basic \citet macro; the former doesn't place parentheses around the year (in authoryear-style citations). To get a semicolon as the separator, issue the instruction \setcitestyle{aysep={; }} in Document --> Settings --> LaTeX preamble.

To generate two citation callouts each with their own notes (e.g., "page 50"), use two separate \citealt -- just like you would use two separate \citet commands if you wanted "ordinary" citation callouts that place parentheses around the publication's year.

In the LyX GUI, \citealt corresponds to the third citation style in the list one gets when right-clicking a citation:

LaTeX code and output

enter image description here

  author = "Bertram Bunks and Daffie Dunks and Fiona Funks",
  title  = "Random thoughts",
  journal= "Circular References",
  year   = 2001,
  volume = 1,
  number = 1,
  pages  = "1-11",
  author = "Conrad Alex",
  title  = "Splits",
  year   = 1999,
\setcitestyle{aysep={; }}


(\citealt[page~50]{bunks01}; \citealt[page~22]{alex99})

natbib set to author-year style with the plainnat style is close, all you need is to change the separator between author and year. So, in Document --> Settings --> Bibliography select Natbib, and Author-year. In Document --> Settings --> LaTeX Preamble, add

\setcitestyle{aysep={ }}

which sets the author-year separator to a normal space. If you want a non-breakable space, so that a line break cannot occur between author and year, use \setcitestyle{aysep={~}}. Finally, set the bibliography style to plainnat in the settings for the BibTeX bibliography.

Regarding your second problem (which perhaps should have been posted as a second question), I don't know if there is a convenient way of doing that within LyX. You can type it manually, by adding the same citation twice with different citation styles, the first displaying only author, the second only year. You could also use egreg's solution to Natbib: Multiple citations with page numbers in one bracket but in that case you have to write the whole thing in an ERT I think, so you can't use LyX' GUI to find and insert the references.

If you want to do that, copy everything from \usepackage{xparse} to \ExplSyntaxOff into the preamble of your document and use the \multicitep macro in an ERT, inserted with Ctrl + L.

Example: The following code block is a .lyx file demonstrating this. Copy everything into an empty text file, save as something.lyx and open in LyX.
