Zoomi.com takes the hundred thousand or so best-selling books off Amazon.com and presents them so you can browse through them on as you would in a physical bookshop. It’s kind of fun zooming in and out – and I enjoyed typing “blogging” into the search field and seeing all the covers of the blogging books lined up together. That actually gives you a pretty good quick overview of the kinds of books out on the subject, because yes, you can often judge a book by its cover. But as Sebastian Mary writes at if:book, it also carries with it the disadvantages of a physical bookshop. I think I’ll be sticking to the non-zooming online bookshops myself.
