Other Book Terms
Anthology - A collection of literary works which may be poems, short stories, plays, songs or excerpts generally by multiple authors.
Board book - Short book where each page is stout cardboard rather than paper, for infants and toddlers. See also rag book.
Bumped - Refers to the corners or spine ends of a book that has been damaged by being dropped or carelessly handled or shelved.
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.
Ex-Library - (EXLIB) Deaccessioned from a Public Library or Collection.
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.
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.
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.
Omnibus Edition - Book containing more than one work by the same author. Commonly two or more components have been previously published as separate books.
POD - Print on Demand is 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.
Rag book - Short book for infants and toddlers, where each page is printed on textile rather than paper. See also board book.
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.
TPS - Trimmed page size (also trim size and trimmed leaf size). The outer dimensions of a page of a finished book, so for A-format, 178 x 111mm.
Uncorrected Book Proof - Bound together with a thick paper cover, usually for promotion or publicity purposes. Book proofs are generally uncorrected. If largely corrected they are referred to as advance copies.
