1. To organize your references, use collections. Under "collections" in the left hand menu, select "new collection", give it a name, and hit enter.
2. Click and drag references from the center column to the Collection to add them.
For quick citations in most text editors, including Google Docs and Word, right click the item you want to cite in Mendeley and select "Copy Formatted Citation." Then, paste it into the document you are composing.
When you download Mendeley, you also have the option to download a plugin for Microsoft Word. This set of tools will appear in the "Ribbon" menu of Word underneath the "References" tab.
This plugin is best used once you have a library of citations and are ready to begin writing a manuscript of any length. To use the plugin, simply start writing your paper. It has two main functions: in text citations, and bibliographies.
In Text Citations
Mendeley comes with all of the major citation styles pre-installed, but occasionally you might have need of a specific one, or a specific edit of a major style. You can do this through the the "View" menu in Mendeley Desktop by selecting "More styles..."
Once within this separate menu, you can look for the title of the style you need by typing in the search bar. Click "use this style" on a new citation style to add it to your software.
You can also find the citation you are already using and right click it to choose "Edit Style." This will take you to the Mendeley Citation Style Language Editor online, which is a complex tool with its own set of user instructions.
