Karen Schneider and others have launched a NLW campaign to assist the imprisoned Cuban dissidents. This is one of the first approaches to this issue that I have seen that focuses on the plight of the prisoners themselves and doesn't make their librarianness [or lack thereof] the central issue. You can work on this project and not have to listen to a lot of polemic vitriol against ALA, you can just help. If you want to work for reform within the US Government and the Helms-Burton Act, this may not be for you. Check out their Freadom Project. Nice going, team.
