The location of the citation in a paragraph differs between the two styles. For humanities footnotes or endnotes, place the raised number at the end of all the material in each paragraph. The citation is often just before the transitional sentence that ends the paragraph. In the case of a short essay that uses the humanities style, a bibliography is a waste of space. Be sure to follow the standard conventions for designating articles versus book.
Books are in italics or underlined .
Johnson does not use MLA style, but does use a similar style that gives the date of publication, which is borrowed from the natural sciences. Do not do this, but use the simpler MLA style. The reason is that dates are not import for the social sciences and take up room. The MLA Handbook or any other style manual explains the style in detail. Place the parenthetical name and page number directly after the material cited, but before the period or punctuation ending the sentence.
