World Book Online includes the Citation Builder tool. Select the type of citation you want to create--for an encyclopedia article, a website, a book, a podcast, a magazine article, a blog entry, a World Book special report--and fill in the bibliographic elements on the worksheet that next appears. Citations are generated in APA, MLA, and Harvard styles.
A free personal registration with World Book's "My Research" is required if you want to save your citations.
