Display tags in widget?

I have a left sidebar menu, in it are some pages. I want my tags to appear as sub-menus to one of the pages. Such that the page is “books” and has a gallery of books in it, and each book is categorized into “level 1”, “level 2”, etc. Clicking on “level 1” takes you to a list of all the level 1 books. How can I do this?
