Yes, donating our old books and notebooks is a very good thing as this can help some needy children in their studies. Some ways to do this are - You can donate your books in some association or some NGO which works for poor or needy children. Another way is that you can donate your books and notebooks in a school which teaches poor children. These ways can help a lot.
