Uncorrected proof (also referred to as galley proof and advance reading copy or ARC) refers to a copy of a book or work before its official publication date. It is often sent out to reviewers, booksellers, and librarians before its official release date to generate pre-publication enthusiasm about its release date.
Uncorrected proofs are printed on lower-grade paper than the final edition of a book and may contain typos or errors that will be rectified in later editions. Because of this, they are generally not sold directly to customers; however, certain publishers release unedited proof copies as part of a marketing gimmick to generate early interest for a title.
Uncorrected proof (sometimes known as an advance reading copy ) is an early version of a book sent out to reviewers, booksellers, and librarians before being published as the final version. It aims to allow them to experience and give feedback before publishing begins.
ARCs can come both digitally and in print form. Digital versions typically take the form of PDFs or e-books; print versions usually feature perfect-bound paperbacks with cover designs unique to their final counterpart. Physical formats of an ARC may differ depending on its publisher; typically smaller than standard paperbacks and with distinctive cover art designs that differ from that found on final copies of a book are usually present.
Uncorrected proofs are an integral component of the printing process and should be carefully reviewed and edited at this stage to ensure a high-quality final product. By carefully proofreading and correcting errors early, printers can avoid costly mistakes that cause delays and frustration later. Furthermore, early identification can reduce reprint costs, saving both time and money over time – reviewing and correcting proofs can save headaches (and money!) in the long run!
