ARC is an acronym used to denote an "advance reader's copy" on a printed preview copy of a book. The purpose of an ARC is to get early reads and create pre-publication "buzz" from booksellers and/or publicity
venues. ARCs are labeled as such ("Not for Resale") and resemble paperback books--they have a near-final version of the actual book jacket
, and usually include promotional copy (such as advertising, marketing and PR plans). ARCs are expensive to produce and distribute, and are usually reserved for major releases.
