An ISBN is assigned to each edition and variation (except reprintings) of a book. For example, an , a and a edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, and 10 digits long if assigned before 2007. The method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering ( SBN) created in 1966. The 10-digit ISBN format was developed by the International Organization for Standardization (ISO) and was published in 1970 as international standard ISO 2108 (the SBN code can be converted to a ten digit ISBN by prefixing it with a zero). Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure; however, this can be rectified later.Bradley, Philip (1992). . The Indexer. 18 (1): 25–26. Another identifier, the International Standard Serial Number (ISSN), identifies periodical publications such as ; and the International Standard Music Number (ISMN) covers for musical scores. History The Standard Book Numbering (SBN) is a 9-digit commercial system created by , Emeritus Professor of Statistics at Trinity College, Dublin, for the booksellers and stationers and others in 1965. The ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker (2017). 9789995788940, Kunsill Nazzjonali tal-Ktieb. . (regarded as the "Father of the ISBN") and in 1968 in the US by Emery Koltay (who later became director of the U.S. ISBN agency R.R. Bowker). The 10-digit ISBN format was developed by the International Organization for Standardization (ISO) and was published in 1970 as international standard ISO 2108. The United Kingdom continued to use the 9-digit SBN code until 1974. ISO has appointed the International ISBN Agency as the registration authority for ISBN worldwide and the ISBN Standard is developed under the control of ISO Technical Committee 46/Subcommittee 9 TC 46/SC 9. The ISO on-line facility only refers back to 1978. An SBN may be converted to an ISBN by prefixing the digit "0". For example, the second edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has - 340 indicating the publisher, 01381 their serial number, and 8 being the check digit. This can be converted to ISBN 0-340-01381-8; the check digit does not need to be re-calculated. Since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with "" European Article Number EAN-13s. Overview An ISBN is assigned to each edition and variation (except reprintings) of a book. For example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, and 10 digits long if assigned before 2007. An International Standard Book Number consists of 4 parts (if it is a 10 digit ISBN) or 5 parts (for a 13 digit ISBN): 1. for a 13-digit ISBN, a prefix element – a GS1 prefix: so far 978 or 979 have been made available by GS1, 2. the registration group element, (language-sharing country group, individual country or territory)Some books have several codes in the first block: e.g. A. M. Yaglom's Correlation Theory..., published by , has two ISBNs, 0-387-96331-6 and 3-540-96331-6. Though Springer's 387 and 540 codes are different for English (0) and German (3); the same item number 96331 produces the same check digit: 6. Springer uses 431 as their publisher code for Japanese (4) and 4-431-96331-? would also have check digit ? = 6. Other Springer books in English have publisher code 817, and 0-817-96331-? would also get check digit ? = 6. This suggests special considerations were made for assigning Springer's publisher codes, as random assignments of different publisher codes would not lead the same item number to get the same check digit every time. Finding publisher codes for English and German, say, with this effect amounts to solving a linear equation in modular arithmetic. 3. the registrant element, 4. the publication element, and 5. a character or . A 13-digit ISBN can be separated into its parts ( prefix element, registration group, registrant, publication and check digit), and when this is done it is customary to separate the parts with or spaces. Separating the parts ( registration group, registrant, publication and check digit) of a 10-digit ISBN is also done with either hyphens or spaces. Figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits.The international ISBN agency's ISBN User's Manual says: "The ten-digit number is divided into four parts of variable length, which must be separated clearly, by hyphens or spaces" although omission of separators is permitted for internal data processing. If present, hyphens must be correctly placed; see ISBN hyphenation definition. The actual definition for hyphenation contains more than 220 different registration group elements with each one broken down into a few to several ranges for the length of the registrant element (more than 1,000 total). The document defining the ranges, listed by agency, is 29 pages. How ISBNs are issued ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for that country or territory regardless of the publication language. The ranges of ISBNs assigned to any particular country are based on the publishing profile of the country concerned, and so the ranges will vary depending on the number of books and the number, type, and size of publishers that are active. Some ISBN registration agencies are based in national libraries or within ministries of culture and thus may receive direct funding from government to support their services. In other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the stated purpose of encouraging Canadian culture. In the United Kingdom, United States, and some other countries, where the service is provided by non-government-funded organisations, the issuing of ISBNs requires payment of a fee. Australia: ISBNs are issued by the commercial library services agency Thorpe-Bowker, and prices range from$42 for a single ISBN (plus a $55 registration fee for new publishers) to$2,890 for a block of 1,000 ISBNs.

Registration group identifier
The registration group identifier is a 1- to 5-digit number that is valid within a single prefix element (i.e. one of 978 or 979). Registration group identifiers have primarily been allocated within the 978 prefix element. The single-digit group identifiers within the 978 prefix element are: 0 or 1 for English-speaking countries; 2 for French-speaking countries; 3 for German-speaking countries; 4 for Japan; 5 for Russian-speaking countries; and 7 for People's Republic of China. An example 5-digit group identifier is 99936, for . The allocated group IDs are: 0–5, 600–621, 7, 80–94, 950–989, 9926–9989, and 99901–99976.See a complete list of group identifiers. ISBN.org sometimes calls them group numbers. Their table of identifiers now refers to ISBN prefix ranges, which must be assumed to be group identifier ranges. Books published in rare languages typically have longer group identifiers.

Within the 979 prefix element, the registration group identifier 0 is reserved for compatibility with International Standard Music Numbers (ISMNs), but such material is not actually assigned an ISBN.

The registration group identifiers within prefix element 979 that have been assigned are 10 for France, 11 for the Republic of Korea, and 12 for Italy.

The original 9-digit standard book number (SBN) had no registration group identifier, but prefixing a zero (0) to a 9-digit SBN creates a valid 10-digit ISBN.

Registrant element
The national ISBN agency assigns the registrant element (cf. ) and an accompanying series of ISBNs within that registrant element to the publisher; the publisher then allocates one of the ISBNs to each of its books. In most countries, a book publisher is not required by law to assign an ISBN; however, most book stores only handle ISBN bearing merchandise.

A listing of more than 900,000 assigned publisher codes is published, and can be ordered in book form (1399, US\$1959). The web site of the ISBN agency does not offer any free method of looking up publisher codes.See Publisher's International ISBN Directory Partial lists have been compiled (from library catalogs) for the English-language groups: identifier 0 and identifier 1.

Publishers receive blocks of ISBNs, with larger blocks allotted to publishers expecting to need them; a small publisher may receive ISBNs of one or more digits for the registration group identifier, several digits for the registrant, and a single digit for the publication element. Once that block of ISBNs is used, the publisher may receive another block of ISBNs, with a different registrant element. Consequently, a publisher may have different allotted registrant elements. There also may be more than one registration group identifier used in a country. This might occur once all the registrant elements from a particular registration group have been allocated to publishers.

By using variable block lengths, registration agencies are able to customise the allocations of ISBNs that they make to publishers. For example, a large publisher may be given a block of ISBNs where fewer digits are allocated for the registrant element and many digits are allocated for the publication element; likewise, countries publishing many titles have few allocated digits for the registration group identifier and many for the registrant and publication elements.Splane, Lily (2002).

Pattern for English language ISBNs
English-language registration group elements are 0 and 1 (2 of more than 220 registration group elements). These two registration group elements are divided into registrant elements in a systematic pattern, which allows their length to be determined, as follows:

Check digits
A is a form of redundancy check used for , the decimal equivalent of a binary . It consists of a single digit computed from the other digits in the number. The method for the ten digit code is an extension of that for SBNs, the two systems are compatible, and SBN prefixed with "0" will give the same check-digit as without - the digit is base eleven, and can be 0-9 or X. The system for thirteen digit codes is not compatible and will, in general, give a different check digit from the corresponding 10 digit ISBN, and does not provide the same protection against transposition. This is because the thirteen digit code was required to be compatible with the EAN format, and hence could not contain an "X".

ISBN-10 check digits
The 2001 edition of the official manual of the International ISBN Agency says that the ISBN-10  – which is the last digit of the ten-digit ISBN – must range from 0 to 10 (the symbol X is used for 10), and must be such that the sum of all the ten digits, each multiplied by its (integer) weight, descending from 10 to 1, is a multiple of 11.

For example, for an ISBN-10 of 0-306-40615-2:


\begin{align}
s &= (0\times 10)   (3\times 9)   (0\times 8)   (6\times 7)   (4\times 6)   (0\times 5)   (6\times 4)   (1\times 3)   (5\times 2)   (2\times 1) \\
&=    0   27     0    42    24     0   24      3   10   2\\
&= 132 = 12\times 11

\end{align}

Formally, using modular arithmetic, we can say:

$\left(10x_1 9x_2 8x_3 7x_4 6x_5 5x_6 4x_7 3x_8 2x_9 x_\left\{10\right\}\right)\equiv 0 \pmod\left\{11\right\}.$

It is also true for ISBN-10's that the sum of all the ten digits, each multiplied by its weight in ascending order from 1 to 10, is a multiple of 11. For this example:


\begin{align}
s &= (0\times 1)   (3\times 2)   (0\times 3)   (6\times 4)   (4\times 5)   (0\times 6)   (6\times 7)   (1\times 8)   (5\times 9)   (2\times 10) \\
&=    0   6     0    24    20     0   42      8   45   20\\
&= 165 = 15\times 11

\end{align}

Formally, we can say:

$\left(x_1 2x_2 3x_3 4x_4 5x_5 6x_6 7x_7 8x_8 9x_9 10x_\left\{10\right\}\right)\equiv 0 \pmod\left\{11\right\}.$

The two most common errors in handling an ISBN (e.g., typing or writing it) are a single altered digit or the transposition of adjacent digits. It can be proved that all possible valid ISBN-10's have at least two digits different from each other. It can also be proved that there are no pairs of valid ISBN-10's with eight identical digits and two transposed digits. (These are true only because the ISBN is less than 11 digits long, and because 11 is a .) The ISBN check digit method therefore ensures that it will always be possible to detect these two most common types of error, i.e. if either of these types of error has occurred, the result will never be a valid ISBN – the sum of the digits multiplied by their weights will never be a multiple of 11. However, if the error occurs in the publishing house and goes undetected, the book will be issued with an invalid ISBN.For example, I'saka: a sketch grammar of a language of north-central New Guinea. Pacific Linguistics. ISBN "0-85883-554-4".

In contrast, it is possible for other types of error, such as two altered non-transposed digits, or three altered digits, to result in a valid ISBN number (although it is still unlikely).

ISBN-10 check digit calculation
Modular arithmetic is convenient for calculating the check digit using modulus 11. Each of the first nine digits of the ten-digit ISBN—excluding the check digit itself—is multiplied by a number in a sequence from 10 to 2, and the remainder of the sum, with respect to 11, is computed. The resulting remainder, plus the check digit, must equal a multiple of 11 (either 0 or 11). Therefore, the check digit is (11 minus the remainder of the sum of the products modulo 11) modulo 11. Taking the remainder modulo 11 a second time accounts for the possibility that the first remainder is 0. Without the second modulo operation the calculation could end up with 11 – 0 = 11 which is invalid. (Strictly speaking the first "modulo 11" is unneeded, but it may be considered to simplify the calculation.)

For example, the check digit for an ISBN-10 of 0-306-40615- ? is calculated as follows:


\begin{align}
s &= (11 - ( ((0\times 10) (3\times 9) (0\times 8) (6\times 7) (4\times 6) (0\times 5) (6\times 4) (1\times 3) (5\times 2) ) \,\bmod\, 11 ) \,\bmod\, 11\\
&=    (11 - (0   27     0    42    24     0   24      3   10 ) \,\bmod\, 11) \,\bmod\, 11\\
&= (11-(130 \,\bmod\, 11))\,\bmod\, 11 = (11-(9))\,\bmod\, 11 = (2)\,\bmod\, 11 = 2

\end{align}

Thus the check digit is 2, and the complete sequence is ISBN 0-306-40615-2. The value $x_\left\{10\right\}$ required to satisfy this condition might be 10; if so, an 'X' should be used.

It is possible to avoid the multiplications in a software implementation by using two accumulators. Repeatedly adding t into s computes the necessary multiples: // Returns ISBN error syndrome, zero for a valid ISBN, non-zero for an invalid one. // digitsi must be between 0 and 10. int CheckISBN(int const digits10) {

       int i, s = 0, t = 0;


       for (i = 0; i < 10; i  ) {
t  = digits[i];
s  = t;
}
return s % 11;

} The modular reduction can be done once at the end, as shown above (in which case s could hold a value as large as 496, for the invalid ISBN 99999-999-9-X), or s and t could be reduced by a conditional subtract after each addition.

ISBN-13 check digit calculation
The 2005 edition of the International ISBN Agency's official manual  describes how the 13-digit ISBN is calculated. The ISBN-13 check digit, which is the last digit of the ISBN, must range from 0 to 9 and must be such that the sum of all the thirteen digits, each multiplied by its (integer) weight, alternating between 1 and 3, is a multiple of 10.

Formally, using modular arithmetic, we can say:

$\left(x_1 3x_2 x_3 3x_4 x_5 3x_6 x_7 3x_8 x_9 3x_\left\{10\right\} x_\left\{11\right\} 3x_\left\{12\right\} x_\left\{13\right\} \right) \equiv 0 \pmod\left\{10\right\}.$

The calculation of an ISBN-13 check digit begins with the first 12 digits of the thirteen-digit ISBN (thus excluding the check digit itself). Each digit, from left to right, is alternately multiplied by 1 or 3, then those products are summed modulo 10 to give a value ranging from 0 to 9. Subtracted from 10, that leaves a result from 1 to 10. A zero (0) replaces a ten (10), so, in all cases, a single check digit results.

For example, the ISBN-13 check digit of 978-0-306-40615- ? is calculated as follows:

s = 9×1   7×3   8×1   0×3   3×1   0×3   6×1   4×3   0×1   6×3   1×1   5×3
=   9    21     8     0     3     0     6    12     0    18     1    15
= 93
93 / 10 = 9 remainder 3
10 –  3 = 7


Thus, the check digit is 7, and the complete sequence is ISBN 978-0-306-40615-7.

In general, the ISBN-13 check digit is calculated as follows.

Let

$r = \big\left(10 - \big\left(x_1 3x_2 x_3 3x_4 \cdots x_\left\{11\right\} 3x_\left\{12\right\}\big\right) \,\bmod\, 10\big\right).$

Then

$x_\left\{13\right\} = \begin\left\{cases\right\} r &\text\left\{ ; \right\} r < 10 \\ 0 &\text\left\{ ; \right\} r = 10 . \end\left\{cases\right\}$

This check system – similar to the UPC check digit formula – does not catch all errors of adjacent digit transposition. Specifically, if the difference between two adjacent digits is 5, the check digit will not catch their transposition. For instance, the above example allows this situation with the 6 followed by a 1. The correct order contributes 3×6 1×1 = 19 to the sum; while, if the digits are transposed (1 followed by a 6), the contribution of those two digits will be 3×1 1×6 = 9. However, 19 and 9 are congruent modulo 10, and so produce the same, final result: both ISBNs will have a check digit of 7. The ISBN-10 formula uses the modulus 11 which avoids this blind spot, but requires more than the digits 0-9 to express the check digit.

Additionally, if the sum of the 2nd, 4th, 6th, 8th, 10th, and 12th digits is tripled then added to the remaining digits (1st, 3rd, 5th, 7th, 9th, 11th, and 13th), the total will always be divisible by 10 (i.e., end in 0).

ISBN-10 to ISBN-13 conversion
The conversion is quite simple as one only needs to prefix "978" to the existing number and calculate the new checksum using the ISBN-13 algorithm.

Errors in usage
Publishers and have varied policies about the use of the ISBN check digit. Publishers sometimes fail to check the correspondence of a book title and its ISBN before publishing it; that failure causes book identification problems for libraries, booksellers, and readers.Lorimer, Rowland; Shoichet, Jillian; Maxwell, John W. (2005). Book Publishing I. CCSP Press. p. 299. ISBN 978-0-9738727-0-5. For example, ISBN 0-590-76484-5 is shared by two books – Ninja gaiden® : a novel based on the best-selling game by Tecmo (1990) and Wacky Laws (1997), both published by Scholastic.

Most libraries and booksellers display the book record for an invalid ISBN issued by the publisher. The Library of Congress catalogue contains books published with invalid ISBNs, which it usually tags with the phrase "Cancelled ISBN". 020 – International Standard Book Number (R) – MARC 21 Bibliographic – Full. Library of Congress. However, book-ordering systems such as Amazon.com will not search for a book if an invalid ISBN is entered to its search engine. often indexes by invalid ISBNs, if the book is indexed in that way by a member library.

eISBN
Only the term "ISBN" should be used; the terms "eISBN" and "e-ISBN" have historically been sources of confusion and should be avoided. If a book exists in one or more digital () formats, each of those formats must have its own ISBN. In other words, each of the three separate , , and formats of a particular book will have its own specific ISBN. They should not share the ISBN of the paper version, and there is no generic "eISBN" which encompasses all the e-book formats for a title. sellbox.com, Retrieved, 9 October 2014

EAN format used in barcodes, and upgrading
Currently the on a book's back cover (or inside a mass-market book's front cover) are EAN-13; they may have a separate barcode encoding five digits for the and the recommended retail price. — including a detailed description of the EAN-13 format. For 10 digit ISBNs, the number "978", the "country code", is prefixed to the ISBN in the barcode data, and the check digit is recalculated according to the EAN13 formula (modulo 10, 1x and 3x weighting on alternate digits).

Partly because of an expected shortage in certain ISBN categories, the International Organization for Standardization (ISO) decided to migrate to a thirteen-digit ISBN (ISBN-13). The process began 1 January 2005 and was planned to conclude 1 January 2007. As of 2011, all the 13-digit ISBNs began with 978. As the 978 ISBN supply is exhausted, the 979 prefix was introduced. Part of the 979 prefix is reserved for use with the code for with an . 10 digit ISMN codes differed visually as they began with an "M" letter; the bar code represents the "M" as a zero (0), and for checksum purposes it counted as a 3. All ISMNs are now 13 digits commencing 979-0; 979-1 to 979-9 will be used by ISBN.

Publisher identification code numbers are unlikely to be the same in the 978 and 979 ISBNs, likewise, there is no guarantee that language area code numbers will be the same. Moreover, the ten-digit ISBN check digit generally is not the same as the thirteen-digit ISBN check digit. Because the GTIN-13 is part of the Global Trade Item Number (GTIN) system (that includes the GTIN-14, the GTIN-12, and the GTIN-8), the 13-digit ISBN falls within the 14-digit data field range.

Barcode format compatibility is maintained, because (aside from the group breaks) the ISBN-13 barcode format is identical to the EAN barcode format of existing 10-digit ISBNs. So, migration to an EAN-based system allows booksellers the use of a single numbering system for both books and non-book products that is compatible with existing ISBN based data, with only minimal changes to information technology systems. Hence, many (e.g., Barnes & Noble) migrated to EAN barcodes as early as March 2005. Although many American and Canadian booksellers were able to read EAN-13 barcodes before 2005, most general retailers could not read them. The upgrading of the UPC to full EAN-13, in 2005, eased migration to the ISBN-13 in North America.
