Final answer:
The correct internal citation for referencing Helen Keller's work would depend on the availability of page numbers and the context of the citation. If page numbers are available, include them; if not, use the paragraph number or author's last name only, as per MLA guidelines.
Step-by-step explanation:
The question at hand regards the correct method for creating an internal citation pertaining to works by Helen Keller in the context of academic writing, specifically adhering to MLA formatting guidelines. The correct internal citation will depend on whether specific page numbers are available, and to what exactly the paper is referencing. For instance, referring to Helen Keller's own writings would require the citation to reflect the specific location within her text where the referenced information can be found.
If a student is citing a specific page from Keller's autobiography, which was later published as a book, the in-text citation should follow the author-page format, for instance: (Keller 23). However, if no page numbers are provided, such as in the case of an online source, the student should use the author's name only or, if paragraphs are numbered, include the paragraph number: (Keller par. 4). If Keller's work is cited as part of another work, for example, an analysis of her works in a scholarly article without page numbering, the internal citation might be just the author's last name: (Keller).
Therefore, when drafting your paper and including internal citations, it is crucial to adhere to the specific guidelines of the citation style being used and provide as much specific reference information as possible to allow readers to find the original source material easily.
