From the campaign page:
You may know of #WeNeedDiverseBooks as the hashtag that went viral after BookCon released its whitewashed author lineup. But since then we've become so much more than just a hashtag. We've incorporated and become an organization dedicated to creating tangible change within the publishing industry, and have been thrilled at the support we've received from organizations across the world. You can read more about our mission here.
Thus far we've been a volunteer corps surviving on moxie alone - but we can do so much more with your help.
