The key point of difference between Amazon`s Kindle and other readers is that Kindle does not have glare when viewed outdoors. As a result, a series of trucks and related events - such as a literary scavenger hunt - celebrated summer by sending a mobile library around New York and adopting one of its most popular piers. Persons could "check out" their favorite e-book from the mobile reader and experience reading it in sunlight. In addition, they could donate their traditional books for the e-reader equivalent. In addition, chapters were solicited to create a composite "Summer in the City" e-book tapping into the concentration of writers in New York City.
