There are only two instances when provisional patent applications are made publicly available. If a non-provisional patent application is filed claiming priority to the provisional patent application and the non-provisional patent application is either (a) published or (b) granted as a patent then a copy of the provisional patent application may be accessed on. As Russ pointed out, you must enter your non-provisional patent application serial number in order to view the provisional patent application.
