?Level 7,? a science fiction book by Mordecai Roshwald about a post-apocalyptic dystopia published by the University of Wisconsin Press in 1959, has gotten a new life in the present thanks to the Amazon Kindle. Krista Coulson, electronic publishing manager for the UW Press, says ?Level 7? was one of the first backlist titles the press published in e-book format, thanks to requests from Kindle users looking for the story.
