Well, either you are going to find you hate the idea of e-books, in case it will not matter about the book and tag panes or you will find you do like e-books, in which case I can just about guarantee your book collection will be "considerably" more than three in pretty short order, especially once you find a source for free classics.
But, you are correct; the book and tag panes are a wee bit of overkill for your present massive collection.
