To avoid plagiarism, you must cite your sources when using them in your papers. Each citation must appear in two places - a brief mention in the body of your paper (the in-text citation) and a full citation in the list of references at the end (the Works Cited citations).
In-text citations are brief, and generally include only the surname of the author and page number.
1 Author: In order to be successful, a woman writer "must have money and a room of her own" (Woolf 4).
2 Authors: Statistics show that the proportion of women who work "nearly doubled from 1950 to 2005" (Rudman and Glick 179).
3+ Authors: Silent women, it is argued, "see blind obedience to authorities as being of utmost importance for keeping out of trouble and insuring their own survival" (Belenky et al. 28).
No Author: Woolf and her husband "established Hogarth Press, their own publishing house operated out of their home" ("Virginia Woolf").
No Page Number: The Bloomsbury Group, of which Virginia Woolf was a member, "openly rejected the old Victorian ideals from their childhoods" (Brooks).
There are also many ways to integrate the quote and brief citation information into the body of your paper:
Parenthetical Citation (Citation parts are all placed at the end of the quote): In some respects, the "retrieval of the human, and of human kinship across the ages, is seen as the novelist’s duty towards the past" (Ellis 173).
Narrative Citation (Citation parts, such as the author's name, are integrated with the sentence): Virginia Woolf argues that "Anon, who wrote so many poems without signing them, was often a woman" (49).
Paraphrase (The content is summarized, rather than quoted): If Shakespeare had an equally talented sister, she would likely have drowned herself for lack of social support in Renaissance times (Woolf 48).
