Usually, these databases cover journals and articles by one publisher only. The advantage is that you have an immediate access to full texts of articles. The search covers all the text, including the full text. This is useful, when you are looking for a rare topic, which is not mentioned in a title or abstract of an article, but somewhere inside the text.
