The first of the articles, written by Huntington, is the cornerstone for this issue. Not only is it a cogent primer of managed care terms, this article also is a comprehensive discussion of the complex managed care scene today. An especially useful aspect of this article is the fact that Huntington provides "links" to several important resources of additional information.
