If you are using an EBSCOHost source, then the citation is already available through the citation page (click the “Cite” link on the right). However, you need to check and make sure that the author’s name is cited correctly because there have been cases where the author’s last name did not come first (as it should).
If you are using a non-EBSCOHost source, and you want to cite it in MLA format, then I recommend using EasyBib.com.
However, EasyBib is not free for APA format, so if you want to cite sources in APA format, then I recommend CitationMachine.net.
In a Works Cited or Reference page, the sources should be sorted alphabetically.
