Several nifty reading charts are out there for keeping track of your progress as you read the standard works (for example, they hand one out with the seminary Scripture Mastery cards). This one, however, is different because it also depicts the larger structure of the Book of Mormon, to help you get the big picture. Most books (the larger ones) have major and minor subdivisions. For example, 2 Nephi is subdivided into the words of Lehi (ch. 1–5), the words of Jacob (ch. 6–10), the words of Isaiah (ch. 11–30), and the words of Nephi (ch. 31–33). That third subdivision—the words of Isaiah—is further subdivided into actual quotes from Isaiah (ch. 12–24) and Nephi’s inspired commentary (ch. 25–30).
These subdivisions are based in part on the Structured Edition of the Book of Mormon—a customized version of the standard works that lays out the (unchanged) authorized text in paragraphs and with headings, so it looks more like a modern novel or textbook. If you’re interested in reading an edition of the scriptures that uses headings to depict this chart’s subdivisions in the actual text as you read, take a look at the Structured Edition of the standard works. You can download it for free.
If you like this reading chart, you may also be interested in the chart showing the original chapter breaks in the Book of Mormon. The first edition Joseph Smith published had different chapter breaks than those we use today (far fewer, in fact). Those original breaks were very likely indicated on the gold plates themselves, so they should be considered when looking for larger connections between passages.
