@EugeneNZ Hi there, like your creative thinking! However, are you likely to use a USB directory on you computer, if you have the internet & could use our website instead?
Good spotting though, our print books have been reduced in size, as part of our Sustainable Business Practices.
Our paper stock is made from timber off-cuts (material that would otherwise have gone to the landfill) & is accredited by the Forestry Stewardship Council. Plus, all of our books are 100% recyclable!
You can learn more about our Environmental Policies here http://www.ypg.co.nz/environmentpolicy.html
Cheers!
