As far as I can see, this is an acceptable Corporate Author BUT a number of works are incorrectly combined.
Most of the Study Guides, Instructor's Manuals and similar are not by the Consortium, but by other named authors (e.g. For All Practical Purposes (Paper): Mathematical Literacy in Today's World had it's guide written by Heidi A. Howard)
