[Highland Park] question for home schoolers here or elsewhere nationwide

I am writing a book on Saving Our Public LIbraries. While it started because of my concern about local libraries, the book is nationwide in focus since many libraries throughout the nation are at risk these days. I want to talk to some home schoolers about the importance of public libraries to them. Also wanted to find out the best national home schooling organization to contact. Any home schoolers here who could help? Or perhaps you have homeschooling friends elsewhere to whom I could talk. I'm happy to call anywhere in the U.S. Thanks very much. janet jai 412-362-7607
