What is an ARC? And how can I get one? - The Sweet Escape
ARC's are Advanced Reader Copies. They are typically uncorrected galleys of a manuscript. Typically very limited ARCs are made available as they are normally sent out to professional book reviewers / bloggers so that these reviewers can read the book and post a review prior to the actual release. This gives a book visibility before it goes on sale... creates a buzz, if you will.
