There's a charity bundle over at the OneBookShelf sites to help raise some money for the Southern Poverty Law Center. As disclosure, Battlefield Press is one of the participants in the bundle.
Edit: I linked to the SPLC donation page, rather than the Bundle. Here's the link to the charity bundle.
From the Southern Poverty Law Center's website:
In the decades since its founding, the SPLC shut down some of the nation’s most violent white supremacist groups by winning crushing, multimillion-dollar jury verdicts on behalf of their victims. It dismantled vestiges of Jim Crow, reformed juvenile justice practices, shattered barriers to equality for women, children, the LGBT community and the disabled, protected low-wage immigrant workers from exploitation, and more.It is a charity that is worth helping out. Find out more about them on their website.
