I am very pleased to see that Martin Hall now strongly supports CC-BY licensing (at least for scientific papers). I am a scientist (unlike most of the RCUK detractors and CC-BY detractors) and support both (<a href="http://blogs.ch.cam.ac.uk/pmr/2013/02/10/why-we-must-support-cc-by-e-g-rcuk-policy-its-good-for-us-and-good-for-the-world/">http://blogs.ch.cam.ac.uk/pmr/2013/02/10/why-we-must-support-cc-by-e-g-rcuk-policy-its-good-for-us-and-good-for-the-world/</a> ). The RCUK policy is about more than money, and, as MartinH says, and I have argued consistently give much greater public good. <br>
<br>It should be noted that CC-NC forbids the use of material for teaching (a commercial activity however benignly carried out). I have been unable to use UK examples (from the Royal Society of Chemistry) in my international lectures as there is no clear licence and the RSC continue to charge for Open Access re-use (I have repeatedly pointed this out but it remains). Only clear CC-BY or CC0 licensing will solve this.<br>
<br>MU indicates that he would like modified CC-* licences for humanities, etc. I am on the Science Board of Creative Commons and we are in the midst of reviewing for CC-* licences so it is a valuable time to make suggestions. It is not, however, easy to use CC licences for limit downstream us. People who argue that CC-NC does this are general mistaken.<br>
