This page provides instructions to writing citations in LaTeX using WinEdt.

Instructions

• Export your bibliography as a .bib file, such as from Zotero.
• Place this file inside the same folder as your .tex file.
• In your .tex file, write the following:

  \begin{document}
  \bibliographystyle{citation style}
  
  \end{document} 

where citation style should be replaced by the citation style of your choice. For a list of citation styles, click here.

• Now, write the following line where you want your bibliography to be placed:

  \bibliography{filename}

where filename should be replaced by the name of your .bib file.

• Under the Tree tab, click Build Tree.
• To create an in-line citation, place your cursor where you want to cite and write:

  \cite{}

and a drop-down list would pop-up, showing the entire bibliography from the .bib file. Select the paper you want to cite and click Insert.
