Medium has announced its acquisition of the Social-based ebook company Glose. Glose is a platform where users can buy and read books, then share notes and highlights with friends. Once the integration is complete, Glose’s library’wo n’t be included in medium’s $ 5 monthly and $ 50 annual subscriptions’.

Glose CEO Nicolas Princen raises the idea of readers being able to jump from an article into a book.’the vision is to create an experience where you can go from one to the next,’ he says.

Medium could show me books written by the author of the article I’m reading. Going further, medium could also find books about the article’s subject and show those to readers who want to go deeper.

Ev Williams spoke to CNN business about making it easier to spin off a blog post from an inspiring Book passage from Glose.

As much the acquisition cost medium is n’t public, it provides a revenue stream for the company outside of its subscription service.
