Take time to review what you've found and read them more completely to confirm if these sources are the most suitable for your research assignment.
You may find it good practice to save many sources along the way and use this stage to decide what is most appropriate to use as your final sources.
If you've decided on final sources, be sure they're properly cited per your professor's instructions!
Zotero provides the ability to save sources from catalogs, databases, and other websites with one click.
You can then organize and edit the citation entries, which makes it great for annotated bibliographies, research papers, and more!
The Citation Style Guide has plenty of information to help you better understand the citation style your professor is asking for.
