BibTeX is both a tool and a file format that is used with LaTeX documents, which are specifically geared towards coding, engineering and mathematics.
Zotero can do a one-time export of citations as a *.bib file. In the drop-down menu, select “File” and then “Export Library…” In the drop-down list of file types, select BibTeX (*.bib). Save your BibTeX file in the same location as your LaTeX files. If you plan on making any changes to your citations, it may be easier to download a plugin like Better BibTeX.

Mendeley can do a one-time export of citations as a *.bib file. Within your "My Library" in Mendeley, select the references you would like to export to BibTeX. In the drop-down menu, select "File" and then "Export"; In the drop-down list of file types, select BibTeX (*.bib). Save your BibTeX file in the same location as your LaTeX files. If you plan on making any changes to your citations, it may be easier to go to your Mendeley Desktop "Preferences," click the "BibTex" tab, and select the box labeled "Enable BibTeX syncing" and any additional options you require.

RefWorks is a citation management tool that other Oregon universities use. RefWorks is a web-based tool that lets you export articles from library databases or RSS feeds to your RefWorks account, which you can then organize online. It also works with other citation management software if you are collaborating with researchers. RefWorks is not free for PSU students and requires an annual subscription.
OHSU students have access to RefWorks through the end of 2016. OHSU Library’s guide on using RefWorks is available on the OHSU library website.
Paperpile is another citation management tool. It is built specifically for the Chrome browser and works on OS X, Windows, Linux and Chrome OS. It works with your Google Apps and integrates with your citations with Google Drive and Docs. Because it integrates with Google Apps, it is very easy to share and keep everything updated on the go.
The downside is that Paperpile is limited specifically to Google apps, and does not work with other browsers or word processors. Paperpile is only free for a 30 day trial, after which you will need to pay a fee of $36/year to use it.
