for example in academic journals or textbooks Page headers and page footers, the contents of which are usually uniform across content pages and thus automatically duplicated by layout software. The page number is usually included in the header or footer, and the software automatically increments it for each page. Pull quotes and nut graphs which might be added out of course or to make a short story fit the layout Table of contents In newspaper production, final selection and cropping of photographs accompanying stories might be left to the layout editor (since the choice of photo could affect the shape of the area needed, and thus the rest of the layout), or there might be a separate photo editor. Likewise, headlines might be written by the layout editor, a copy editor, or the original author. To make stories fit the final layout, relatively inconsequential copy tweaks might be made (for example, rephrasing for brevity), or the layout editor might make slight adjustments to typography elements like font size or leading. Floating block A floating block in writing and publishing is any graphic, text, table, or other representation that is unaligned from the main flow of text. The use of floating blocks to present pictures and tables is a typical feature of academic writing and technical writing, including scientific articles and books. Floating blocks are normally labeled with a caption or title that describes its contents and a number that is used to refer to the figure from the main text. A common system divides floating block into two separately numbered series, labeled figure (for pictures, diagrams, plots, etc.) and table. An alternative name for figure is image or graphic. Floating blocks are said to be floating because they are not fixed in position on the page at the place, but rather drift to the side of the page. By placing pictures or other large items on the sides of pages rather than embedding them in the middle of the main flow of text, typesetting is more flexible and interruption to the flow of the narrative is avoided. For example, an article on geography might have "Figure 1: Map of the world", "Figure 2: Map of Europe", "Table 1: Population of continents", "Table 2: Population of European countries", and so on. Some books will have a table of figures—in addition to the table of contents—that lists centrally all the figures appearing
