Databases are usually collections of journal and magazine articles, dissertations, reviews, and abstracts. Using a database allows users to search for information in an organized collection. The user benefits from this organization because it provides more relevant results, through the use of subject headings and descriptors. Users can also search for keywords in specific fields, such as author and title, and limit their results using various criteria.
Databases also provide information in known sources, for example, printed magazines and journals. The content of databases has undergone a review process and the information is more reliable than information found on the Internet. Often databases provide access to full-text magazine and journal articles.
