It looks like Christmas has come early as far the publisher Routledge is concerned. From now until the end of the year, they are offering free access to the 250 most read journal articles in the education field. That's a lot of free content! To browse the collection, simply click here.
If you're a fan of free content (and which researcher isn't?) then you may also be interested in this previous post about open access articles, this post which provides details about the Access to Research service, or this post about other non-journal online resources.
