Can you help me with an MLA style Work Cited Page or direct me to the appropriate website?

I didn't think it would be so hard to get some straight forward examples to show me how to do this. I just need to know how the work cited entry on the work cited page should look for a book, for an art journal and for an internet source with no identifiable author. I see examples of work cited pages but how do I know which work cited entry corresponds to which type of source? Do you see my dilemma? Please help!
