Rather than having to edit your BibTeX bibliographic entries manually, you can manage your references with a reference management program, such as Mendeley, and then export references in BibTeX format.
Mendeley reference manager brings the best functions of Endnote and Zotero and perhaps is the easiest reference management system to combine with LaTeX. If you follow these steps, after a few setting changes (and no extra downloading), you will be able to have an automatically syncing BibTeX file for your LaTeX document.
Begin creating your Mendeley reference list. If you need help to create a Mendeley reference list please refer to the LibGuide for advice.
In My Library create a new folder and insert your required references. Note: it doesn't have to be the completed list as this method allows you to add references at any stage.
Click on the Tools tab then select Options
Press the BibTeX tab at the top of the pop up page.
Tick the Escape LaTeX special characters button
Tick the Enable BibTeX syncing
Then tick the Create one BibTeX file per group option
IMPORTANT You now need to press the Browse... button to select the destination of your BibTeX file. This needs to be in the same folder as your LaTeX file.
Click the Apply button, then OK.
Now any references you add to your linked folder in Mendeley will automatically be added to the BibTeX file in the LaTeX folder
In terms of citation keys, Mendeley automatically generates in the format of [AuthorYear].
