Just a very quick note to say that Crop Genetic Resources as a Global Commons: Challenges in International Law is available in Google Books. Edited by Michael Halewood, Isabel Lopez Noriega (both of Bioversity International) and Selim Louafi (formerly of the ITPGRFA), and with dozens of people contributing to 19 chapters ranging over the whole philosophy, history, design and context of the International Treaty, it’s a really important resource.
Thanks for this useful update.
