Each of these documents offers useful concepts and strategies for reading scholarly journal articles. Different disciplines observe different standards. Articles in the humanities rarely have the formal structures described on many of these sites. For example, the "literature review" often consists of a paragraph or two in which the authors name previous scholars who have asked related questions (and then declare their inadequacies). But they always explain the focus of their question, justifying it as worthy of their attention, are explicit about the stages of their analysis, providing evidence for each claim, and document their sources.
