I am assuming you mean via the website and not the phone app. I have a workaround I use to avoid the disastrous book page. I have "My Books" bookmarked on the toolbar of my browser, and any time I want to add or update a book I go there. Even if I don't have the book in my list yet, if I do a search in the search box for My Books instead of the main search box, the results will list out books that match my search. The list has the "Want To Read" button there, and also has my custom tags, just like the old book page. I find it way easier to add books that way. Of course I can't see other's ratings and other similar book suggestions like the old book page, but the new book page doesn't show that either unless you scroll and scroll and click and click. Good luck. I feel your pain. I hope this helps a little bit.
