I'm not quite sure you 1) don't discuss your changes, 2) don't explain your changes and additions in your edit summaries, and most importantly 3) don't understand what makes a reliable source. Not a single source you've added qualifies. --Walter Görlitz (talk) 19:37, 12 February 2013 (UTC)[reply]
Please find a reliable source. That PDF does not have an author and so could have been written by anyone, as student, a blogger or even you. Please stop now and learn what constitutes a reliable source! --Walter Görlitz (talk)
