two different kinds of citations in the same document

Question

I am using LyX with the default "article" document class. All the citations look as bracketed numbers [1], [2], etc. I want to have two different citation formats in the same document, according to the context, for example:

"It is impossible to solve the problem exactly (Author1, Year1), however, recently an approximate solution has been suggested by Author2 (Year2)".

How can I do this?

This can be achieved with the natbib package, and its authoryear option. You also need a natbib-compatible bibliography style, like plainnat. Then, the commands \citep{...} and \citet{...} do exactly what you want. No idea, though, how this is accomplished with LyX. — mafp, Jul 05 '13 at 09:53

In LyX, go to

Document Settings > Bibliography > Natbib

Then when you go to

Insert > Citation

you can change how the citation appears by changing the Citation style box. It will give you a preview of how it will look in the PDF.

I did this, and now all my citations look e.g. like this: "(author?) [15]" (i.e. a boldface string "author? was added... not the name of the author). This happens no matter what format I choose in Insert->Citation... – Erel Segal-Halevi Jul 07 '13 at 04:24
Can you post a .lyx minimal example? – scottkosty Jul 07 '13 at 04:25
Note: The bibliography itself looks fine - all authors and years appear correctly. Only the citation doesn't work. – Erel Segal-Halevi Jul 07 '13 at 04:28

Ah, I found a solution - right-click on the bibliography, and change the "style" from "plain" to "plainnat" :) – Erel Segal-Halevi Jul 07 '13 at 04:37

Glad it works now. For future LyX + BibTeX problems, note that LyX 2.1 should report Natbib errors. You can still see the BibTeX log in LyX by going to Document LaTeX Log and changing it to BibTeX. – scottkosty Jul 08 '13 at 02:58

See below example:

\documentclass{article}
\usepackage[authoryear]{natbib}
\begin{document}

It is impossible to solve the problem exactly \citep{au1}, however,
recently an approximate solution has been suggested by \citet{au2}.

\begin{thebibliography}{1}

\bibitem[Author1(2009)]{au1}
Author1, {\it PLE} 3(6):19--64, 2009.

\bibitem[Author2(2010)]{au2}
Author2, {\it PLE}, 4(7):119--164, 2010.
\end{thebibliography}
\end{document}

As the OP uses LyX, this is at best a partial solution, as it doesn't say anything about where the different required elements is found in the LyX GUI. (Also, an unrelated note, don't use \it, \bf etc, but the new \itshape, \bfseries etc., see Does it matter if I use \textit or \it, \bfseries or \bf, etc.) – Torbjørn T. Jul 05 '13 at 18:20
