Once you have performed your search, you will need to identify the articles you wish to export. This can be done by selecting articles individually, multiple at a time, or your entire results.
Then you will follow these steps to export your selection(s).
1. After selecting the article(s), you wish to save, you will click "Export Selected Citation(s)"

2. This will open a pop-up window that will allow you select multiple options. You will be asked to choose what format you wish your exports to be in. If you're unsure of which one to choose, check out Exporting Formats.
Once you have made the appropriate selection(s), you will then click "Download".

This should successfully download your file in your desired format!
