The service is only in beta testing right now, but it's already getting support from numerous school districts, publishers and contributors. The Folger Shakespeare Library is offering material to help teach Shakespeare's plays, for instance, while the Department of Education is giving prospective college students a leg up by providing its scorecards. While it may be odd to see Amazon serving as an educational gateway, it's clearly not messing around -- this could be a go-to hub for teachers who'd rather not search the web (or whip up their own content) to get digital material.
