It looks like you have a dozen or so PDF’s for download, I’d create a page in WordPress containing links links to each PDF. You can store the PDF’s in the WordPress media library. Supported file types:

Once you have your PDF’s uploaded to the Media library, look for the “File URL” it will look something like this:
http://www.yourdomain.com/wp-content/uploads/2012/08/yourfile.pdf
