 The Reader tool has two components.  The first is the Text Reader, where text is displayed for reading with minimal formatting. Scrolling will enable you to fetch more content, hovering over a word will display its frequency within the document (*not* within the corpus), and clicking on a term will search for it within the Reader and in other tools if applicable.

 The second componenet of the Reader tool is the Prospect Reader, which looks like a series of colored boxes below the Text Reader. The Prospect Viewer provides an overview of the entire corpus, which is particularly useful if your corpus consists of multiple documents, like ours does!  The bars represent each document in the order they appear in the corpus, and the relative length of each document is represented both the height and width of the bar. A verticle blue bar will indicate the current position of the Text Reader in the corpus as you browse. You can click anywhere along the Prospect Viwer to jump to that point in the text.

 You can specify search terms either by clicking on works in the Text Reader, or entering them into the query box at the bottom of the tool. When a search term is entered, a sparkline will appear within the bars of the Prospect Reader showing the relative frequency of that term accross the corpus.

 Each series in the graph is coloured according to the word it represents. A legend at the top of the graph displays which words are associated with which colors. Clicking on words in the legend will affect their visibility in the graph. Hovering over any point in the graph activates a popup with information about that point, including the word, its frequency, and the document or document segment. For corpora consisting of multiple documents, like ours, double-clicking on a point allows you to "drill down" or view the frequency of that word accross a single document within the corpus.
