Most databases are indexes . It does not give you the text of books. They don't give you the articles. Search engines provide links to web pages. They don't provide the pages.
Some databases provide data or the full text of articles.
In addition to indexing, some databases provide statistics or data. However, most often databases that provide content, provide text. That is, some databases provide the full text of articles that are indexed in that database. Most of the databases in the Scribner Library do NOT provide the full text of articles. Even databases, such as EbscoHost , that are considered full-text databases usually do not provide the full text for all of the articles which they index.
