A library database is an electronic collection of published works. Library databases have been curated to help you research different topics. Most databases will have full text and abstracting/indexing for academic journals, magazines, newspapers, and other resources.
Full text means that the database will provide digital access to a copy of the articles in the journal.
Abstracting and indexing means that the database provides basic information about articles in a journal. This information usually includes: title, author, publisher, publication date, topic, and an abstract.
An abstract is a summary of the article. It is a very helpful tool for determining if the article you found in the database is right for you.
