While Google Books has not generated the buzz the iPad, Kindle and Nook have — likely because it has no handheld device (yet) and relies on PDF-like pages, not the flowing and malleable text of the other devices — it can be an easy way for subscription sites to re-purpose and sell their content to a wider audience.Through the Google Books Partner program, you can upload your white papers and PDF downloads and have them indexed in Google Search as well as on the Google Books subsite. Users can then purchase your Google Book through your website.For step-by-step instructions on joining the Google Books Partner program — and why you should avoid becoming a Google Books Seller — check out the how-to article on our sister site, Subscription Site Insider.
