End of the Sum paragraph

let?s modify our formats Reduce function to emit the number of pages in each book as the value.

Should read:

let?s modify our formats Map function to emit the number of pages in each book as the value.

Note from the Author or Editor:
In Chapter 2: MapReduce, "Reduce" section, "Sum" subsection, the sentence:

"?let's modify our formats Reduce function to emit the number of pages in each book as the value."

Should say:

"?let's modify our formats Map function to emit the number of pages in each book as the value."

The word "Reduce" needs to be replaced with "Map".
