The New York Times publishes a good bestsellers list, but doesn't provide stats, www.nytimes.com/pages/books/bestseller
I don't believe such a list exists. Publishers Weekly lists bestsellers in various categories, but if you want exact sales data, you have to get it from individual publishers.
i've heard it's exist , the list of book sales by their ISBN (International Standard Book Number ) - it's how mags and papers gets their lists, no?? still looking..
They get data samples from publishers - even the major mags don't get a list of sales figures for every book out there. As I've already said, you'll need to get data directly from publishers to pull what you're asking for. Read this article to give yourself some more background on how those "best seller lists" actually come about - if a resource like what you're asking for existed, those lists would be the same - there's a reason they're not.
