Google Books, iBooks, Nook, Kindle, Kobo, Sony... you'd figure the e-book field was crowded enough, right? Well, if you're specifically in the market for children's stories, things might look a little less packed. We guess that's why Scholastic is attempting to enter the fray with Storia, an e-reading app and store designed for kids. As part of a massive digitization effort, the company has launched Storia in beta for Windows and the iPad, alongside a market of over 1,000 titles. By the time it officially launches in the fall Scholastic hopes to have a fully stocked digital library of over 2,000 books loaded with interactive features. You can download the beta now with five free e-books by hitting up the more coverage link.
