Ask Indies is a collaborative project by indie booksellers on Twitter, designed to use their expert knowledge to help you find books. Ask a question about books, and booksellers will respond with recommendations, ideas, and opinions.
Any Twitter user can publicly ask booksellers a question by coding a post with the hashtag #askindies.
Every book page on IndieBound.org now has an Ask Indies button which links to a Twitter form—here's an example. The book's URL and the #askindies hashtag are automatically entered for you. You can tweet your question directly from the site.
Of course, you can also use the #askindies hashtag wherever you post to Twitter -- through Twitter.com, or a desktop or phone client.
