include the full text of articles or links
to the full text, while others give you citations
only or a mix of full text and citations.
Citations include brief information about an article, like the article title, author, journal title and date. Sometimes an abstract, a brief summary of the article, is included with the citation.
Make sure to keep track of your citations (use Zotero or EndNote) because if you use the information from an article in your research paper, you will need to document that article in your bibliography.
Below is a sample citation. Title is the article title, and Source is the journal name, year, volume and pages where the article is found. The abstract is a summary of the article.
