Question about Citation?

It is common and informative to cite the author's name, the publication and the year and often the page number the first time he/she is paraphrased: i.e. (L. Phillips, "The Beginning of Life" (2007) at 114) [if the publication is a book, then the title is underlined and quotation marks are not used]. Thereafter, whenever there is a reference to the same book, it is adequate to just name the author and the page" i.e. (Phillips at 341). If you are referring your reader to a publication on the general topic, then you may leave off the page reference. If the same book has been published by more than one publisher or in several editions, your page reference is only meaningful if your reader is told which publisher and/or edition: i.e. (L. Phillips, "The Beginning of Life", Scott-Mifflin, 3rd ed., at 114). Once again, when you next cite the same book, you may simply state (L. Phillips at 563). If you are writing an essay about just one book or article, then you may simply name the author, publisher, edition and year in the title, at the beginning or as a footnote and subsequently cite just the author and page (Phillips at 327). However, even in that situation, inclusion of paraphrase or quotes from other authors or publications requires a more informative citation.
