== "Page" parameter in citations, and "dead link" tag == 

 Please note that there is an important distinction between the "pages" and "page" parameters in book citations.  "Pages" refers to the total number of pages in that publication, whereas "page" refers to the page on which a quote of the information being referred-to is located.  In several of the edits you made, you reversed these (added a "s" and removed a "s") which rendered the cite incorrect.  Also, did you even bother checking the hyperlink before you tagged it as a , because I just tested it, and it works fine?
