http://www.noodletools.com/noodlebib/index.php NoodleBib is an online tool
that simplifies the process of creating and editing MLA and APA-style
source lists. There is a subscription fee for a school district or for
personal use. It gives you the explanation as well. It does not do the
parenthetical citations, just the source list, hanging indent and all!
