I've just seen this
www.prideandlessprejudice.org/available-book-bundles
An American organisation which donates book bundles to schools and pre-schools in the US. I wholeheartedly applaud the notion of kids books featuring people everyone can relate to. Having read some of the descriptions though, they are a mixed bag and some seem unbelievably regressive (based on the description alone, which I'm aware is dodgy ground).
