Box 54No numbers appear on the pages of the article

  • If all of the pages of an article in PDF (Portable Document Format) have no page numbers:
    • Count the total numbers of pages of the text
    • Follow the count total by "p."
    • Place the number and " p." in square brackets, such as [12 p.]
    • End page information with a period
      Example: [20 p.].
  • If the article is in HTML, XML, or another unpaginated format:
    • Count the number of screens, paragraphs, lines, or bytes, whichever is most practical, or print out the article and count the number of pages
    • Precede the total with the word "about" for all except the number of paragraphs and bytes because screen size and type fonts vary
    • Place the count total and the measure used in square brackets
    • End with a period placed outside the closing bracket
      • [about 6 screens].
      • [about 23 p.]
      • [10 paragraphs].
