I have tried many of the sites in this book and I have not seen one that has what I am looking for. I went to many sites and it would not let access or didn't have what I was looking for. I get so frustrated. I wish the free books offered were not so out dated or learning books. Last time I saw so many books that were for learning was when I went to the school library 25 years ago. Sorry I have not found it to be very useful , yet.
