A friend of mine who works for Pearson Education recently told me about We Give Books. This year alone, the Pearson Foundation, in partnership with the Penguin Group, is planning to donate more than a million books to children who do not have books. You can drive the effort simply by reading free books on-line at We Give Books. You'll find picture books for children through age ten, with a good mix of fiction and non-fiction. There are read-aloud books, and books for older children to read independently. New books are added each month, and you'll find special seasonal offerings, as well.
Did I mention it's free? (I know that I did. Three times. I just want to over-emphasize that it doesn't cost you anything to be a hero.)
Aside from contributing to the very worthy cause of child literacy, if you're a picture book author you'll be able to "research read" within your genre. If you're a parent, you can teach your child about philanthropic giving as you read with him or her. Older children can experience the joy of giving as they read books on-line on their own. Teenagers could even design a service project around We Give Books. Everybody wins, but only if you log on now, register, and start reading.
It's free, by the way.
