For people who don’t know:
NetGalley is a site where publishers give reviewers books for free! Usually they’re Advanced Reader Copies (ARCs) or books with new re-releases or new campaigns for publicity. All you have to do is request the book from the publisher with a simple click of a button, and if the publisher likes your NetGalley profile and associated links (I recommend linking your review blog and/or personal blog, Twitter, and Goodreads) they’ll approve you! Then you just give an honest review through NetGalley and your blog.
It’s very simple and straight-forward, and it’s books for free!
(on a related note, I got approved for my first book by Riptide Publishing through NetGalley today, so that’s exciting!)
