CliffsNotes and SparkNotes both publish summaries of various works of literature on their websites. Both websites feature chapter summaries of two or three chapters at a time.
CliffsNotes has a browse tab that allows readers to explore texts by category and popularity. Selecting the Literature tab shows the reader a list of texts by title and author. CliffsNotes provides an "At a Glance" overview of the text selected, with a clickable menu to the left that provides chapter summaries in two- to three-chapter increments. CliffsNotes also includes character analysis, information about the author, study tools and links to critical essays about the text in question.
SparkNotes lists topics related to the text in a list of clickable links. In addition to chapter summaries, SparkNotes provides plot overviews, character lists, analysis, study tools and information about how to cite their review materials.
