LaTeX Guide : Citing with BibTeX
In order to cite works in LaTeX documents, you should use the file format of BibTeX . Most databases and even current citation managers such as RefWorks, Endnote and Zotero can export citations in the BebTeX format. BibTeX files get exported as simple text files with a .bib extension. Reed College has a good guide at: http://web.reed.edu/cis/help/latex/bibtex.html
Once you have BibTeX files, you then establish the type of style you want to use in your document. Here is a good guide from Reed College: http://web.reed.edu/cis/help/latex/bibtexstyles.html
You can get many styles from CTAN (the archive for all things TeX), but many of them are out of date so a simple Google search may be better.
BibTex with Zotero, RefWorks, EndNote, & Mendeley
Transferring citations from a different citation manager into a BibTeX file is quite easy. The process varies depending on the type of citation manager.
1. Zotero: Left-click on the folder of citations you would like to transfer into a BibTex file. Select export collection, then "BibTeX." Save the .bib file to your computer.
2. RefWorks: Go into the RefWorks "output style manager" and add the BibTeX format to your favorites. Next, click on "bibliography," select a folder of citations, and select "BibTeX" as the output style. A new tab will open up in your browser with each citation in BibTeX form. Copy and paste the information into a text document and save the .bib file to your computer.
3. EndNote:In the toolbar, click on the citation management dropdown menu. Select BibTeX export. The BibTeX format will appear in the preview box for each citation. Copy and paste into a .bib file.
4. Mendeley: once in Mendeley desktop, select "tools," then options. Next, select "enable BibTeX syncing." Select the type of BibTeX file (whole library, collection, or document) and a path will be created to a .bib file of your Mendeley citations.
