Query: Too many errors and sloppy editing.

While this book contains useful information, the book contains too many errors for it to be used for any but the most casual purpose. Meaning is confused by bad editing and sloppy table construction. On page 589 the Atlantic Ocean is listed as 5.5 percent of total (total of what?), while the Pacific Ocean is listed as 48.9 percent of total. One might assume that the reference is to area since the column to the left lists the Pacific's area as 64,186,300 sq. mi.and the Atlantic's area as 33,420,000 sq. mi. But as anyone can see if 64,186,000 is 48.9 percent then 33,420,000 is certainly not 5.5 percent. The total row at the bottom of the table list a sq.mi. total figure and 100.0 percent. The respective columns to not add to those figures. What was left out? Other problems are double words and spelling errors. Don't buy the book.
