The process for linking a PDF file for download from a Web site isn’t terribly difficult but it does depend on what web editor you are using. It sounds as if you have created this PDF using Adobe’s online PDF maker which will store the PDF for 72 hours before deleting it. If so, you will need to first download the PDF to your computer so that you have it. Adobe offers a few different options for doing so.
Okay, now that you have a local copy of the PDF file, you will need to have it hosted somewhere. If you have your own Web site, simply upload the PDF to the Web site. The process for uploading PDFs is similar to any other upload you do but does depend on the web editor in use. Generally, you’ll store it in a folder of your Web site. For example, if you use Microsoft Office Live for your Web site, the PDF should be uploaded to the “Documents Gallery.”
Once the PDF file is uploaded to your Web site, you will then have an actual address for the file. For example, depending on where the PDF file is stored, the URL to the file might look something like this:
www.mywebsite/manual.pdf
Now, enter your URL into the address bar to be sure that the link works. If so, you’re ready to begin using it as a link in your Web site, in forms, in emails, etc. Again, the process for adding hyperlinks to a Web site varies depending on what editor you are using. You may want to simply display the URL or you may want to have descriptive text instead such as “Download PDF Here.” Using Microsoft Office Live as an example again, you would go to the page editor, click “Hyperlink,” click “My Documents,” and then find the manual.pdf file in the list of uploaded documents. In the “Display Text” box, you would type in the descriptive text. Other Web editors have similar features. Likewise, if you use Web or e-mail forms, you would need to insert the URL to your PDF in much the same manner - again using the features for hyperlinking that are provided in the particular application you are using.

The short answer is yes, I can. That is to say, the original authorship appearing on any website can be protected by copyright. This includes all of the content that is found on a particular website including the literary works, photographs, illustrations, sound recordings, and any other content or form of authorship that can be protected by copyright. More specifically, once online works that are accessible over a communication network (the Internet) including websites, FTP sites, and homepages become tangible and fixed, they are open to copyrighting.
