What is the difference between MLA 6 and MLA 7 and include examples of citations please?

MLA 6 automatically underlines the source with out italicizing it.MLA 7 italicizes the source but doesn't underline it. Most teachers prefer that you use MLA 6 because they want the source underlined not italicized.If you go to easybib.com and enter a book title and authors name then click cite this it will set it up for you.Scroll down and it will show you the cited citation then you can click on MLA6 or MLA 7 Or APA and it will change it to whatever format you choose.That way you will be able to see good examples of the different formats.

Do not use MLA7 better to use MLA 6.
