Book Sizes

A-format - Generally a UK term. Standard book format (TPS = 178 x 111mm or 7 1/64 x 4 3/8 inches), typically used for most small-format paperbacks.

B-format - Generally a UK term. Standard book format (TPS = 197 x 130mm or 7 3/4 x 5 1/8 inches), slightly larger than A-format, typically used for more upmarket or literary paperbacks.

C-format - Generally a UK term. Mostly a large-format paperback, though there's no universal agreement on exact size (commonly it's Royal-sized, though it often means (TPS = 216 x 159mm or 8 1/2 x 6 17/64 inches).

Demy - (occasionally Demi) A standard book format (TPS = 216 x 135mm or 8 1/2 x 5 5/16 inches), usually hardback, often used for library edition hardbacks and more literary hardback fiction (cf trade paperback). Slightly smaller than the more common Royal format. Pronounced as in 'deny'.

Mass Market - Generally a US term but is increasingly applied to A-format paperbacks in the UK. Small-format paperback edition of a book, usually commercial fiction, intended to sell in large numbers (TPS = 171mm x 105mm or 6 3/4 x 4 1/8 inches). Slightly shorter and narrower than an A-format.

Rack size - US equivalent of A-format but slightly taller and narrower. Can also be termed mass market paperbacks. Usually (TPS = 197 x 106mm or 7 3/4 x 4 11/64 inches).

Royal - A standard book format (TPS = 234 x 153mm or 9 7/32 x 6 1/32 inches), usually hardback, used for most hardback fiction and general non-fiction. Slightly larger than Demy size. See also trade paperback.

Trade Paperback (TPB) - A large-format paperback, usually Royal or Demy size. In fiction publishing, a trade paperback version is often published after the hardback but before the main mass market paperback version. In Australia, a trade paperback is often published instead of a hardback. US: trade paperback is often used to mean what in the UK would be a B-format paperback, and contrasts with an rack-sized mass-market edition.

Other Book Terms

Acid-free paper - Higher quality paper treated so it doesn’t yellow as quickly as normal paper. It yields a neutral or basic pH (7 or slightly greater). The active acid pulp is eliminated during processing. It is also lignin- and sulfur-free.

Activity Book - generally aimed at children, which contains interactive content such as games, puzzles, quizzes, pictures to colour and other elements that involve writing or drawing in the book itself. The book may, or may not, have a loose narrative or contain other non-interactive elements structured around the interactive elements. Activity books may be made for entertainment, education or a mixture of both. Specific types of activity books include colouring books and puzzle books. A book is normally referred to as an activity book if it combines a variety of interactive elements and does not fall neatly into one of these more specific categories.

Anthology - A collection of literary works which may be poems, short stories, plays, songs or excerpts generally by multiple authors.

Barcode - A conventional ‘Bookland’ barcode on a book has the ISBN printed above the stripes, with the EAN at the bottom. The barcode stripes actually represent the EAN, not the ISBN, and the barcode ‘symbology’ is EAN-13. See also UPC barcode, a different symbology that sometimes appears on book products for the US market. Why ‘Bookland’? EANs typically have short prefixes that indicate the country of issue of the EAN (eg a 50 prefix indicates a British EAN – though it doesn’t mean the item was manufactured in the UK). All ISBNs are by nature international, so a 978 prefix is used in the EAN to indicate a fictitious country called Bookland; 2) Other types of barcode (different symbologies) can appear on cartons containing multiple products, and on pallets, shipping labels etc, for example ITF-14 and EAN-128 barcodes.

Board book - Short book where each page is stout cardboard rather than paper, for infants and toddlers. See also rag book.

Book Plate - An ownership label, usually placed inside front cover. Many have become collectible due to the designer or owner; others actually lower the value of books printed in the last 50 or so years, especially book plates that can be purchased in batches of 50 or 100 and a space left for the owner’s name to be penciled or inked-in.

Bumped - Refers to the corners or spine ends of a book that has been damaged by being dropped or carelessly handled or shelved.

Chapbook - Small, inexpensive books produced from the 17th century until today, originally sold by “chapmen”, peddlers, and hawkers. Contents usually of a popular, sensational, juvenile, or moral / educational character.

Chapter Book - Fairly modern term referring to books for older children which are organized into chapters, as opposed to “picture books”, which often are not.

Chipped - Small pieces broken off of a dust jacket or binding.

Closed Tear - A tear with no material missing. It could also mean a tear repaired and closed with Japanese tissue or other such type of paper used for page repairs in the trade.

Cocked - If, when looking down on the head of a book, the corners are not square it is said to be cocked or rolled. Also known as a spine slant. (Note: cocking can also involve a book’s spine being slightly twisted or non-vertical at either end that is not severe enough to cause spine slant.)

Dampstain - A stain left on a cover or pages after having been exposed to water.

Ding - A small bump or dent leaving an impression, sometimes caused by careless handling or storage.

Dog-Eared - Worn or ragged, usually referring to the edges of pages. Corners of pages are turned down like a dog’s ear, often to mark one’s place while reading.

EAN - European Article Number. Now officially called the EAN.UCC. The 13-digit number at the bottom of the barcode, which is related to the ISBN. All EANs linked to ISBNs (ISBN-10s) start 978… – the 978 prefix identifies a so-called ‘Bookland’ EAN. Why? Because many other EAN prefixes identify countries. ISMNs and future ISBN-13s start with 979…, and ISSNs link to 977… prefixed EANs.

Edgeworn - Wear along the edges of hardback book covers.

Edition - A group of books printed without changes to the content (originally from a single set of printing plates). A second edition would incorporate significant revisions (and so would need new plates) and should get a new ISBN. Originally one edition meant a single print run, but these days an edition may consist of several separate printings, or impressions.

Erosion - Loss of paper or cloth caused by a slow and steady wear, as opposed to a chipping or tearing.

Ex-Library - (EXLIB) Deaccessioned from a Public Library or Collection.

Ex-Libris - From a private library, as opposed to a public library. Could also indicate a bookplate or a stamp.

Fading - The color of some book covers fade or become less intense when exposed to light.

Foxing - A term describing the age-related spots and browning seen on paper. Although it is a bit unsightly, foxing does not affect the actual integrity of the paper.

Hardcover or Hardback (HC, HB) - A book whose case is made of stiff boards, as opposed to wrappers.

Impression - A single print run of a book, as in 'third impression', the third batch of copies to be printed and bound. The impression number is usually marked on the copyright/imprint page, often with a sequence of numbers such as '4 6 8 10 9 7 5 3', where the lowest number indicates the impression (in this case, the third). All books in an impression are manufactured at the same time and are identical. There can be several impressions in an edition, all sharing the same ISBN.

Inscription - When an author or someone associated with the book signs and/or handwrites a dedication, etc. e.g. "To my beloved Elizabeth, John Steinbeck"

ISBN - International Standard Book Number. Unique identifier for a book, or more specifically, of a tradeable item within the book trade. A different ISBN is required not only for each title (or work), but for each edition and binding (or manifestation) eg hardback, paperback, revised second edition all need different ISBNs. Different impressions, however, share the same ISBN. The first element (number) in a 10-digit ISBN or the second element (the number/s after the 978 or 979) in a 13-digit ISBN is the Identifier Group which is assigned to mark either a publisher's place of business or the language used for the book. It is handy to know about this identifier so you don't buy a foreign language book by accident sight unseen. The english language identifier is almost always a '0' or a '1' (e.g. 0-330-28498-3 or 978-0-330-28498-1). Sometimes the book can be in english language with another country identifier such as '81' for India but the listing should always advise that it is english language in these cases. The second element in a 10-digit ISBN or the third element in a 13-digit ISBN is the Publisher Code (e.g. 0-330-28498-3 or 978-0-330-28498-1) which is unique to a specific publisher. It can be from 1 up to 7 digits with the title number making up the remainder of the ISBN except for the very last digit. You can search the Global Register of Publishers with the Publisher Code or Name of the Publisher to find more details. The very last digit in the ISBN is a check digit and is a form of redundancy check used for error detection, the decimal equivalent to a binary 'check bit'. The ISBN Agency responsible for issuing ISBN numbers for Australia is Thorpe-Bowker.

ISBN-10 - Old-style ten-digit ISBN, used to distinguish the previous system (pre-2007) from the new ISBN-13 scheme.

ISBN-13 - Revamp of the ISBN numbering system introduced in January 2007, where the old-style ISBN-10 has been replaced with 13 digits, the new scheme is called ISBN-13 and starts with 978 or 979.

ISSN - International Standard Serial Number. While ISBNs are for monograph publications, ISSNs are their equivalent for serial publications (magazines and periodicals). See also EAN.

Loose - When a book has been read carelessly or too often, and has become loose and sloppy in its binding.

Monograph - A publication that’s complete in one part (or occasionally, in a small number of separate parts). Individual books (or occasionally, series of books) are monographs. cf serial publication.

Omnibus Edition - Book containing more than one work by the same author. Commonly two or more components have been previously published as separate books.

Paperback (PPB, PB) or Softcover - A book bound with flexible paper covers; usually a term reserved for mass-market publications.

Perfect Binding - Used in paperback books, trade paperbacks and magazines that have too many pages to be stapled. The page edges are glued together, then placed in the covers. This is a less expensive process than traditional bookbinding and stapling.

Print on Demand (POD) - A process in which copies of a book are not printed until an order has been received, allowing books to be printed singly or in small quantities of between 1 to about 200 copies.

Provenance - (from the French provenir, 'to come from/forth') is the chronology of the ownership, custody or location of individual copies of books.

Rag book - Short book for infants and toddlers, where each page is printed on textile rather than paper. See also board book.

Reading Crease - A crease down the spine of a book (usually a paperback).

Recto - A right-hand page, when a book is open and facing the reader. The other side of the recto is the Verso.

Remainder - These books have been liquidated by the publisher at greatly reduced prices. Copies of remaindered books are marked by the publisher or distibutor and have varied over the years. Today most remainders are marked with a stroke with a felt-tipped marker across the top or bottom of the book's pages near the spine.

Rubbed or Rubbing - Where color has been worn from portions of the binding or dust jacket. It is also used to indicate rubbed cloth covering the boards to the point where the material of which the boards are made is showing through.Wear caused to the edges of the book or dust jacket as a result of shelf friction. See Shelf Wear.

Scuffed - Like rubbed, but more damage has occurred.

Series - Group of linked titles sharing a common series title (eg seven titles in C. S. Lewis’ Chronicles of Narnia). Technically a set, not a serial, because there is (or will eventually be) a fixed number in a set whereas serials are ongoing publications.

Shelf Wear - The wear that occurs as a book is placed onto and removed from a shelf. It may be to the tail (bottom) edge of the covers as they rub against the shelf, to the dust jacket or exterior of the covers (when no dust jacket is present) as the book rubs against its neighbors, or to the head of the spine which some use to pull the book from the shelf.

Slipcase (SLC) - A box built to house and protect a book, leaving the spine exposed.

Soiling - A gathering of dust or dirt usually caused by handling.

Spine - The backbone, or back, of the book where the title (if present) is displayed when it is standing upright on a shelf.

Anatomy of a Book

Backstrip - (Sometimes used as a synonym to Spine) A strip used by binder to reinforce the back of folded sheets in the binding of the spine.

Binding - Material used as a protective cover for a book (e.g.: leather, cloth, buckram, paper, etc.)

Book Block or Text block – The block of internal pages that make up the book.

Book Cover or Book Board - The front and back covers of books are often referred to as book covers or book boards or book panels as they are often made of bookbinding board and cover the book, today typically a cardboard base covered with cloth, paper, or leather.

Dust Jacket or Dust Wrapper or Book Jacket (DJ, DW) - First used during the 19th century, the original purpose of the dust jacket was to protect the cover of books from scratches and dust which could have been made from fine leather, linen cloth, silk or other expensive materials. It wasn’t until after World War I when booksellers and publishers realised the correlation between well designed book cover jackets and book sales, during this time an explosion of book cover designs hit the market. Found only on hardcover books, the dust jacket will normally be made from paper or plastic (or plastic covered paper) with the ends of which wrapped inside the book cover.

Edges – The edges of the leaves and the textblock as a whole. The three outer sides of the text block when a book is closed: fore-edge, top edge or head, and bottom edge or foot. On more expensive books you will likely find the fore edge has been painted with a hidden painting (known as foredge painting or art) or has gilt edges (smoothed and painted, normally with gold leaf or gold paint).

End Paper (End Sheets) – Endpapers are the first and last pages of the book which which glued to the cover boards (front and back). Often these end papers will be of heavier weight and decoratively patterned often marbled with a cloth hinge for reinforcement. Often referred to as a pastedown or end sheets; paste-down is the page which has been glued to the board and the other side is known as a free endpaper

Other than providing improved aesthetics to the internals of the book, end papers or pastedowns also help to counteract the warp of the bookbinding board which happens during the drying stage of apply the cover material. You will often only find end papers in hard-backed books.

Foot - The bottom edge of the text block.

Head - Top edge of the text block.

Headband & Tailbands– Headbands are coloured threads (normally mercerized cotton or silk) which are wrapped around a core of some sort (normally vellum backed with leather) and are then sewn through the signatures, filling space left between the spine and the book block. Their original purpose is to help lessen damage to the book when it is removed from a shelf by it’s headcap. It also helps to some degree in keeping the sections upright. Headbands (and tailbands) are often referred to as endbands. Modern headbands are used for decorative purposes only and are normally glued to the top of the book block. In the 12th and early 13th centuries, headbands were combined with a leather tab. Conventional cloth or silk headbands came later in the 16th century.

Hinge – The Hinge of a book is the section between the cover boards and the spine. It’s the part that bends when the book is opened.

Joint - The Joint of a book is the small groove which runs vertically down the book itself between the book boards (book cover) and the spine. It bends when the book is opened and is only seen on hardcover books. Also called a French joint or French groove, groove, gully, channel, and outer joint.

Leaves – Two pages of a book (1 sheet) is referred to as a leaf, front (‘recto’) and back (‘verso’).

Raised Bands - Raised Bands were originally the result of cords (or thongs) used during the sewing process which were affixed to the signatures and used to hold the book covers on. Later on in the binding process the spine or backbone would be covered and the bands would be raised above the rest of the spine. This method of binding is less common today, as a result faux bands are used purely for decorative purposes.

Signatures – Signatures are stacks of two or more pieces of paper which are folded and grouped together ready for sewing. Each of the signatures are bound together individually and later bound together as a whole forming the textblock. You will only find signatures in hard cover books. Also sometimes referred to as gatherings.

Spine (textblock spine) – The spine is where the signatures and textblock are bound. Usually the spine will contain important book information so it can be easily found when up on the shelf in book stores or libraries, information might include the book’s title, name of author and publishers name or logo. Also known as the back, and backbone. A traditional sewn spine will usually be backed, glued and lined with cloth or paper.

Tail – The Tail is the bottom part of the book.

Title Page - At the front of a book (usually the first or second page), containing such important information as the author, title, and typically, the city where the book was published, the publisher, and date.

Top Edge - Head of the text block.

Wire Lines and Chain Lines – In the early days of paper making wet pulp was laid in a kind of wire mesh frame and the water was shaken out of it, the paper made using this process was called Laid Paper. The wide-spaced lines on the frame were known as chain lines and were typically spaced about 1 inch apart; the closer spaced lines perpendicular to the chainlines were called the wirelines and were typically about 1mm apart. On older books which used paper made via this technique you can visibly see the marks left by the wire and chain lines. Today it is only very expensive paper which is made in this way, usually by hand.
