I'm a "Friend" of the Sunnyvale Library. I help sort books, and help with booksales. Books are my friends (I think I learned that in 3rd grade). I get more for myself than I can plow through in my allocated free time, and our boys have WAY too many books (if that is possible).
I was looking for a new non-profit to help out after Second in Command was born, as I could no longer teach English as a Second Language because it simply took too much of my mommy time away. It was hard enough after the Heir Apparent was born, but with two, I couldn't slice the time out any more. And the good news is, now that they're a bit older, they come to all the sales, love to pick out books, help me stock the table at the library, and are "regulars" in the library. We sort through their books twice each year and give the ones they don't like any more back to the library as a donation. This seems pretty wonderful to me in the Big Scheme of Things, and I hope they will continue as they grow older to appreciate giving back to the community.
