This emphasis by collectors on First Edition Collecting is of course based on the fact that book collecting is generally based that the earliest the printing the better as far as desirability and thus value. There is a practical basis for book collecting focusing for the most part on the fact that at one time books were printed with relatively soft lead metal plates that would begin to show wear with use. Because of this, later editions or printings made from the original printing plates would have a better print quality that was easier to read as well as being more attractive. Over time, even though printing technology developed more durable materials for printing, what was considered the 'best' and most desirable copy or state of any book is the First State of the First Printing. Contemporary reasoning behind the value attributed to a book's earliest printing is generally based on the fact that it is assumed to be one of the closest version's to the author's intent and this also gives earliest printings their greatest desirability. The result is that for 'First Edition' collecting, 'the earlier the better' is a basic rule of desirability and therefore value.
One of the most interesting variants of early printings is the manuscript copy and related pre-publication printings. Manuscript copies are of course the very closest to the author's original intent. Often they contain additional markings and changes reflecting the author's thinking and creative work. Essentially, there is only one manuscript copy though the scarcity of this most desirable variant of the states of a published book is only accessible to institutional collectors or other major collectors of authors' personal papers and writings. Their uniqueness makes manuscript collecting impractical to consider for the general book collector, unless they have almost limitless funds available with which to build their collection. There is a slightly later state of a book's first printing that is considered pre-publication and which is still quite scarce, even in relation to a first printing of an author's early work, nonetheless, it is usually availability if only for a short time to perceptive collectors. This state of a published book is most commonly called the uncorrected proof.
Uncorrected proofs were originally produced as an aid to the original typesetting for a book's first printing. The author and one or more proofreaders would usually edit these proofs and in order to provide space for edition, proofs were produced in the form of what are called galley sheets with a long black space below the text on each page. Unfortunately for collectors, an uncorrected proof with the author's notes and revisions is about as unique and rare as an original manuscript copy. Often though, multiple printings of uncorrected proofs would be produced to be distributed to influential reviewers in order to develop interest in an upcoming work by a new author or an existing author's new book as well as for soliciting 'blurbs' or short endorsements by notable writers suitable for printing in promotional material or on book dust jackets. Unfortunately galley proofs are awkwardly sized because of the nature of their production, being particularly long to aid the addition of editing notes. As time passed, these new paperback inspired 'Cranes' or 'Uncorrected Proofs' have generally come to be called 'Advance Reader Copy' or 'ARC' printings and they are frequently as well bound as most trade paperbacks. It is important for collectors to note that even though the cost of production for Advance Reading Copies is less than advance copies made up by binding typeset sheets or by sending out production copies before the release date as advance review copies, the small production runs of all Advance Reading Copy editions still made each copy relatively expensive to produce. Usually a small production run of ARCs will cost about as much as a full production run of five thousand or so trade bound copies. The advantage for a publisher is that these ARCs or proof copies are currently the best way to distribute a book to potential reviewers or others who are influential in generating interest in an upcoming title.
The lesson for collectors interested in investing in ARC/proof editions is that the window of time in which ARC/proof copies are available at reasonable prices is relatively brief. It is also important to note that a typical ARC/proof copy will always be many times scarcer than even the smallest print runs of first edition books. For collectors of contemporary literature, a genre that did not really take off until the late 1970s or early 1980s, it is probably best for a serious, patient collector to speculate on the most promising writers. If a collector builds his or her collection carefully, ARC/proof copies will always represent textually significant versions of authors' works as well as being commercially more scarce and unusual than even traditionally desirable first trade printings have been.
Advance Reading Copy and Uncorrected Proof collecting highlights
Not uncommonly, ARCs are produced in more than one version. Often the earliest version of ARC/proof editions takes the form of a plain paper cover with no more than a simple textual description of the title, publication date, and author. Usually a later ARC/proof edition, when there are multiple printings of it, will have a glossy cover, closer to or even identically matching the final publication graphics of the book's dust jacket. A good rule of thumb is to assume that plain paper copies are produced in significantly smaller printings than later glossy issues. For the publisher, this differentiation reflects different intended purposes. The plain paper ARC/proof editions are usually used for generating author's corrections and revisions as well as for soliciting 'blurbs' from established writers. The glossy later ARC/proof editions are primarily used for promotional purposes and are sent to sales reps, bookstore chain buyers, and influential reviewers.
It is also important to note that, generally, there is no reliable way to interpret publishers’ labeling of ARC/proof copies for indications of significant textual changes between ARC/proof printings. Generally, ARC/proof printings have come more and more to represent publisher's marketing efforts. Because of this as well as changes in printing and binding technologies, traditional processes of book production, which have in the past proceeded from galleys, to uncorrected bound proofs, to advance reading copies, to publication copies, are unlikely to be religiously followed by contemporary publishers. The various typical names publishers give to ARC/proof printings and which collectors will most likely encounter include but are not limited to: Uncorrected Manuscript, Uncorrected Bound Galleys, Uncorrected Page Proofs, Uncorrected Proof, Uncorrected Proof Copy, Uncorrected Advance Proof, Advance Uncorrected Proofs, Advance Copy, Advance Reading Copy, Advance Reader's Copy, Advance Reader's Edition, and Advanced Reading Copy. As previously noted, this nomenclature is unlikely to denote actual printing states of modern ARC/proof copies with corresponding variations in textual content between printings. Variation in text content within a book's ARC/proof printings is most likely to occur between its plain paper ARC/proof printing and a later slick-cover ARC/proof version.
