Adding tags to a book

I don't think there's any other way to add and edit cookbook tags, but one shortcut I always take is to manipulate the link to quickly skip to the page I need. So if you go to My Bookshelf and click 'next page', then the link will look like this:
http://www.cookbooker.com/bookshelf/337/kaye16?books&orderby=sort_title&ordersort=asc&page=2
See that number at the very end of the link? Just change it into the page no. you think you need, i.e. for a book starting with S, that might be page 9 or 10.

Back to binary search! Tnx

Speaking of tags: Do we really want the tag: ebook, or epub, etc.?
I saw one book in Cookbooker with one of those tags, but the book I own is hardcopy.
At the time, it seemed to me that ebook should somehow be a private tag to the one owner, but not for all other members who might own same in hardcopy. ? ? What do we think and how do we handle if book listed is ebook and we have it also, but in hardcover? And, is there a way to have private tag or note to self?
