Cheryl Strayed, in her book Wild: From Lost to Found on the Pacific Crest Trail asks: “Who am I? we’d ask one another over and over again, playing a game in which the person who was “it” had to think of someone, famous or not, and the others would guess who it was based on an infinite number of yes or no questions”.
In case the author of the quote is not famous, or you think that your reader might not identify him, you should describe the major of his expertise, for instance, psychologist, economic analysts etc.
The main reason not to quote the exact author's point of view is that it may lead to making the list of quotations instead of a paper. Moreover, a reader might not catch your personal idea or opinion on the topic in the sea of the author's opinions.
Please remember that it’s crucial to analyze every quote by mentioning your point of view. It may represent that you understand the meaning of the quotation used.
Example: In Wild: From Lost to Found on the Pacific Crest Trail, Cheryl Strayed states: “Nineteen and pregnant, she married my father.» NB! Do not use a semicolon (;) instead of a colon (:) because it's a grammatical mistake.
(b) You might use an explanatory or introductory phrase, however, it's not a complete sentence. Using this way, don't remember to separate the sentence with a comma.
Example: Cheryl Strayed changed her opinion when she says, “My prayer was different now: A year, a year, a year.”
(c) You might make the quotation as a part of your own sentence using no punctuation between your words and the words of the quote.
Example: Cheryl Strayed described her childhood as an adventure by mentioning that “She lived in five different states and two countries before she was fifteen.»
(d) You might use short quotations, such as two or three words in the middle of your own sentence.
Example: Cheryl Strayed was absolutely shocked and had nothing to say, being «so transparent and effusive». *Quotations: "Wild: From Lost to Found On the Pacific Crest Trail"
