“Downloading and distributing for free is not even half
the story. As the licence is SA, everyone is free to make changes
to them – say farewell to the days of textbooks with
US-specific references or out of date pricing. Does the example in
the text book refer to buying a penny white loaf at Banbury Cross?
Why, then change it to $2:00 wholemeal loaf in Sydney, a $3.80
milkshake at Ettalong Beach (for school children in that area) or
even something from the tuckshop of the specific school it’s
used in. If there is something wrong with a chapter, take it out
and replace it with a better chapter. Over time such books will
reach optimal quality – perhaps even in the absence of
structured review (in that bad variants will be less used by
teachers).”
