Authors have long used excerpts to promote their books, but it's never been all that easy to share a snippet. Most of the time authors have had to either copy the snippet to their site or embed a Kindle sampler.
Now there is a new option. Buk.io is a platform where authors can upload a copy of their book and embed links to the best parts. Those links can then be shared online.
I just got an email from its developer.
Buk.io lets any publisher/author upload an ebook and make it available either in a browser or a mobile app. This flexible platform currently provides over 50,000 public domain and paid books, as well as the ability to search Wikipedia from the platform. For publishers/authors, it is easy to use, as they can upload ePUB files for free and set up prices as they see fit. Authors and publishers get 70% of any revenue from sales and 30% goes to buk.
Buk has a number of examples over on Twitter of excerpts embedded in Tweets. I would show you one here but the tweet doesn't play well with WordPress.
