We are also witnessing a considerable increase in new specialized literature. The most important of these is the standard work Twin Screw Extrusion by J. L. White [44]. It is a rich source of information, both about the historical development and the state-of-the-art technology, as well as about patent literature and specialized publications. A few examples [45,46] from the wide-ranging specialized literature on the subject of co-rotating extruders should be mentioned here.
