I came across a site last year and when I found this I was so happy cause I can type up anything and down load it and now I'm going to share it with you. It was like this as for years I found it hard to get anything unless you pay for it. You can find close to a lot of things you my want. I do know it does take time for something to be added and it can take a long time. I don't mean you will find what you like but there is so much more to the site. So if you want to get all the free stuff and it is in a PDF format
