Quick! Get On the Harry Potter Bandwagon and Ride

More Harry.

The Wall Street Journal reports on publishers efforts to squeeze the Harry lemon dry; works of non-fiction such as “The Making of the Potterverse: A Month-by-Month Look at Harry’s First 10 Years” by Edward Gross, and George Beahm’s “Muggles and Magic: An Unofficial Guide to J.K. Rowling and the Harry Potter Phenomenon.”

On July 21, titles that speculate on the series’s ending will be “worm food in the landfill,” according to John Granger, author of “Unlocking Harry Potter: Five Keys for the Serious Reader.”
