The most basic and reliable way to cite using Zotero is to generate a citation that is copied to your clipboard and then paste it into a document.
1. Select the item (or items) you want to cite.
2. Right-click and scroll down to the Create Bibliography from Item(s) option.
3. Select the appropriate reference style, choose Bibliography, and then choose Clipboard below. Zotero can also output your bibliography as a file.
4. Check your reference for correctness! Like any auto-generated citation, there can often be mistakes. This relies on the quality of referencing information taken from the database or website. This information can be corrected by selecting the item in question and altering the reference element fields that appear under the Info tab.
