The Jo Timeline History Learning Journal features one main timeline spanning from prehistory to the 2060’s, varying in scale from approximately 100 years per inch, down to 1 year per inch.  This main timeline is broken into sections with eight pages between each:  four blank dot-grid pages for general notes, and four pages of blank timelines for creative use such as for recording events within individual empires, wars, or other timeframes.  These independent timelines are placed perpendicular to the main timeline to avoid confusion and to allow the user to create a slightly longer timeline per page.  Additional blank timelines and note pages appear at the end of the book, along with a specialized index showing the years covered on each page, as well as the time scales used.
