When citing sources it is important to cite them in two different ways; an in-text citation within the body of your paper and on the works cited page at the end of your paper.
When citing a novel on the works cited page in MLA format you can follow this format:
Author's Last name, First name. Book Title. City of Publication: Publisher, Year of Publication. Medium of Publication.
So, the novel, 1984 would appear as follows:
Orwell, George. 1984. London: Secker and Warburg, 1949. Print.
When citing a website on the works cited page in MLA format you can follow this format:
Editor, author, or compiler name (if available). Name of Site. Version number. Name of sponsor or publisher, date of resource creation (if available). Medium of publication. Date of access.
So if you were citing the eNotes website if would appear like this:
"Study Guides, Lesson Plans, Homework Help, Answers & More - ENotes.com." Enotes.com. Enotes.com, n.d. Web. 23 Nov. 2015.
When creating an in-text citation:
It is important that you include a parenthetical citation after you implement a quote in your paper. Typically they look like this, (Orwell 100). Make sure that the parenthetical citation comes after the quotation marks. Furthermore, you can follow the same in-text citation rules for a website (Author 100). Lastly, if you cannot find the author (particularly for websites), it is ok to use the title of the work you are citing.
