010 : INTERNATIONAL STANDARD BOOK NUMBER
Mandatory	No
Repeatable	Yes
First Indicator	blank (not defined)
Second Indicator	blank (not defined)
Description	This field contains an International Standard Book Number and a qualification which distinguishes between ISBN when more than one is contained in a record. The field corresponds to the ISBD Standard Number (or Alternative) and Terms of Availability Area. The field may contain the terms of availability and/or price, even if it does not contain an ISBN.
Notes	ISBN structure: The ISBN is a unique number applied to a published item according to the provisions of ISO 2108. The ISBN consists of four distinct parts, each of which is separated by a hyphen or space. Hyphens are recommended in UNIMARC. The four parts are: Group identifier: Allocated to each country or group of countries or language groups by the International ISBN Agency. International organizations, e.g., the UN, also have their own group identifier. Publisher identifier: Allocated to each publisher by a National or Regional ISBN Agency. Title identifier: Allocated to each title (and each edition and format of each title) by the publisher. Check digit: calculated on the basis of the other 9 digits of the ISBN. All digits of the ISBN are numeric except the check digit which may be numeric or a roman numeral X (capital X, representing a numeric value of 10) ISO 2108 gives the standard specifications of the form of the ISBN. Verification of check digit: To check for accuracy of an ISBN: take each digit and multiply by a number whose value depends on the position of the digit (the 'weight'), add the results and divide by 11. If the answer is not zero then one or more of the digits is wrong. Using EX 9 as an example: ISBN ' ' 0 1 1 8 8 4 0 9 4 X (i.e. 10) 'Weight' ' ' 10 9 8 7 6 5 4 3 2 1 Result ' ' 0 9 8 56 48 20 0 27 8 10 -- total 186 186 is not exactly divisible by 11, so the ISBN is incorrect. Data format: The letters ISBN, which are usually found printed with an ISBN on the item, should not be entered in field 010. Any ISBN which is found to be wrongly printed on the item can be entered in subfield $z, Erroneous ISBN, which is provided to give access to records that may have been requested by an erroneous number appearing on the item. Hyphens are inserted to separate the four separate parts of the number in the $a or $z subfield. No other punctuation is permitted. The purpose of the hyphens or spaces in the ISBN is to separate the distinct parts. When an ISBN is displayed in a catalogue entry the inclusion of the hyphens or spaces is mandatory. Many national agencies do not store the hyphens or spaces in the machine-readable record since they can be generated by algorithm if the range of publisher identifiers which have been allocated is known. When records are exchanged internationally the recipient of records may not always know the range of publisher identifiers allocated within the group represented by the first part of the ISBN. Therefore it is recommended that hyphens always be included in the ISBN in field 010 to ensure their display on output. Strictly, each book has one ISBN. However, there are circumstances in which a single record may need to include more than one ISBN, depending on the policy of the cataloguing agency. Examples of situations in which multiple ISBN might appear in a record are: where a publisher issues a work in more than one binding or physical format, each with a different ISBN, and a single record is created by the agency encompassing more than one of these 'editions', where a single record is created for a multipart item (multi-volume monograph) and different ISBN have been assigned by the publisher to each volume, or to each volume and to the set as a whole; where a single item is published, or published and distributed, by more than one entity, each of which has assigned a separate ISBN to the item. In order to distinguish between ISBN when there is more than one in a record, qualifications may be added to one or more of them, according to the practice of the agency preparing the record. Terms of availability and price are often related to each ISBN. Thus this information is recorded in the same field. Punctuation is included with the data as required. The field should be repeated for each valid ISBN. It should also be repeated for an invalid ISBN unless that invalid ISBN clearly relates to a known valid equivalent entered in the record, in which case the invalid ISBN will be entered in the same field as its corresponding valid ISBN (EX 8, 9). Some agencies use the ISBN as record identifier and enter it in the field 001. In those cases the ISBN should be entered additionally in field 010.

011 : INTERNATIONAL STANDARD SERIAL NUMBER (ISSN)
Mandatory	No
Repeatable	Yes
First Indicator	blank (not defined
Second Indicator	blank (not defined
Description	This field contains the ISSN as assigned by an ISSN Centre, any ISSN which has been assigned and cancelled, details of terms of availability and/or price. It corresponds to the ISBD(S) Standard Number (or Alternative) and Terms of Availability Area, although the Key Title is entered in field 530.
Notes	The ISSN is a unique and unambiguous identification number for serials assigned in accordance with ISO 3297. The system for allocating ISSN is controlled by the ISSN International Centre based in Paris. National Centres allocate ISSN to new serials from a batch of numbers allocated to them by the ISSN International Centre, and communicate them to the Centre. Data format: An ISSN consists of eight digits. These are the Arabic numerals 0 to 9, except in the case of the last or check digit where a roman numeral X (capital X) can occur. Since ISSN are likely to be used in the same context as codes designed for other purposes, such as the International Standard Book Number (ISBN) or control numbers, a distinction must be preserved in the form of presentation when printed or displayed. An ISSN is, therefore, preceded by the letters 'ISSN' and a space, and appears as two groups of four digits separated by a hyphen, for example: ISSN 1234-5679. The check digit is always located in the extreme right position, and is calculated on a modulus 11 basis using weights 8 to 2. The letters ISSN are not included in field 011 in the UNIMARC record, though the hyphen is. Detailed specifications for the ISSN and calculation of its check digit are found in ISO 3297. The calculation of the check digit is similar to that needed for ISBN (see field 010). Punctuation: A hyphen should separate the fourth and fifth digits of a valid or cancelled ISSN. No other punctuation should be present. Punctuation for the $b and $d subfields is entered in these subfields according to the practices of the agency preparing the record. Multiple ISSN: Any ISSN that is wrongly assigned and then cancelled or wrongly printed is entered in subfield $y Cancelled ISSN or $z Erroneous ISSN respectively. Such ISSN should be entered in the same field as the correctly assigned ISSN. Those agencies following ISSN International Centre practices for making serial records will always have only one valid ISSN in field 011 of their records. Those agencies with different practices for making serial records may have records which contain more than one valid ISSN in repeated 011 fields. Some agencies use the ISSN as record identifier and enter it in field 001. In these cases the ISSN should also be entered in field 011.

Notes	A fingerprint is a means of identifying older monographic publications constructed by taking groups of characters from certain pages in order to make each publication uniquely identifiable. Since no definitive formula for fingerprint has been determined by international agreement, various forms of fingerprint will be considered acceptable. It is recommended to use a method of fingerprint construction found in Fingerprints = Empreintes = Impronte.

013 : INTERNATIONAL STANDARD MUSIC NUMBER (ISMN)
Mandatory	No
Repeatable	Yes
First Indicator	blank (not defined)
Second Indicator	blank (not defined)
Description	This field contains an International Standard Music Number and a qualification which distinguishes between ISMN when more than one is contained in a record. The field corresponds to the ISBD Standard Number (or Alternative) and Terms of Availability Area. The field may contain the terms of availability and/or price, even if it does not contain an ISMN.
Notes	ISMN structure: The ISMN is used to identify music publications, whether available for sale, hire, gratis or for copyright purposes only, according to the provisions of ISO 10957. Each separately available constituent part of a publication must receive its own ISMN. An ISMN consists of the letter M followed by nine digits. Whenever it is printed or written, the number is preceded by letter ISMN. In countries where the Latin alphabet is not used, an abbreviation in the local script may be used in addition to the Latin letters ISMN. The ISMN is divided into four elements, two of which are of variable length, each of which is separated by a hyphen or space. Distinguishing element: The letter M distinguishes the ISMN from the ISBN. Publisher identifier: Designates the publisher of a given music publication. It is allocated to each publisher by a national or regional ISMN agency. Item identifier: Identifies an edition of a work and the various items within it. An item, in the terms of the Standard, is one separately saleable or available or obtainable constituent part of a music publication. Check character: This is a single digit at the end of the ISMN that provides an automatic verification of the correctness of the ISMN. It is computer calculated. Verification of check character: The check character is calculated on a modulus 10 with alternating weights of 3 and 1 assigned from left to right beginning with the letter M prefix. The letter M counts as 3. This means that each of the first nine characters of the ISMN - i.e. excluding the check digit itself - is multiplied by an alternating sequence of the numbers 3 and 1 from left to right and that the sum of the products thus obtained, plus the check digit, must be divisible without remainder by 10. For example: Publisher prefix Title Number Check digit ISMN M 3 4 5 2 4 6 8 0 5 Weight 3 1 3 1 3 1 3 1 3 Products 9 3 12 5 6 4 18 8 0 = 65 Total: 65 + 5 (check digit) = 70 As 70 can be divided by 10 without remainder M-345-24680-5 is a valid International Standard Music Number. Data format: The letters ISMN, which are usually found printed with an ISMN on the item, should not be entered in field 013. Any ISMN which is found to be wrongly printed on the item can be entered in subfield $z, Erroneous ISMN, which is provided to give access to records that may have been requested by an erroneous number appearing on the item. Hyphens are inserted to separate the four parts of the number in the $a or $z subfield. No other punctuation is permitted. The purpose of the hyphens or spaces in the ISMN is to separate the distinct parts. When an ISMN is displayed in a catalogue entry the inclusion of the hyphens or spaces is mandatory. Many national agencies do not store the hyphens or spaces in the machine-readable record since they can be generated by algorithm if the range of publisher identifiers which have been allocated is known. When records are exchanged internationally the recipient of records may not always know the range of publisher identifiers. Therefore it is recommended that hyphens always be included in the ISMN in field 013 to ensure the display output. Strictly speaking, each music publication has one ISMN. However, there are circumstances in which a single record may need to include more than one ISMN, depending on the policy of the cataloguing agency. Examples of situations in which multiple ISMN might appear in a record are: where a publisher issues a work in more than one binding or physical format, each with a different ISMN, and a single record is created by the agency encompassing more than one of the 'editions', where a single record is created for a multi-volume publication and different ISMN have been assigned by the publisher to each individual volume in the set and to the set as a whole; where a single item is published, or published and distributed, by more than one entity, each of which has assigned a separate ISMN to the item. In order to distinguish between ISMN when there is more than one in a record, qualifications may be added to one or more of them, according to the practice of the agency preparing the record. Terms of availability and price are often related to each ISMN. Thus this information is recorded in the same field. Punctuation is included with the data as required. The field should be repeated for each valid ISMN. It should be repeated for an invalid ISMN unless that invalid ISMN clearly relates to a known valid equivalent entered in the record, in which case the invalid ISMN will be entered in the same field as its corresponding valid ISMN (EX 3). Some agencies may use the ISMN as record identifier and enter it in the field 001. In those cases the ISMN should be entered additionally in field 013.

016 : INTERNATIONAL STANDARD RECORDING CODE (ISRC)
Mandatory	Yes
Repeatable	Yes
First Indicator	blank (not defined)
Second Indicator	blank (not defined)
Description	This field contains an International Standard Recording Code and a qualification which distinguishes between ISRCs when more than one is contained in a record. The field corresponds to the ISBnot a government publicationD Standard Number (or Alternative) and Terms of Availability Area. The field may contain the terms of availability and/or price, even if it does not contain an ISRC.
Notes	ISRC structure: The ISRC is used to identify an audio, video or audio-visual recording, according to the provisions of ISO 3901. Each separately available constituent part of a publication must receive its own ISRC. An ISRC consists of twelve digits. Whenever it is printed or written, the number is preceded by letter ISRC. In countries where the Latin alphabet is not used, an abbreviation in the local script may be used in addition to the Latin letters ISRC. The ISRC is divided into five elements, two of which are of variable length, each of which is separated by a hyphen. Country code: A two-letter country code assigned from ISO 3166-1. First owner code: An alphanumeric 3 character code assigned by nominated agencies. Year of recording code: The last two digits of the year. Recording code: This consists of three or four digits, assigned by the first owner. If there are fewer than ten recorded items the code will be in the range 0000-2999; if there are more than nine the code will be in the range 300-999. Recording item code: This consists of a number from 0-9 if the recording code has four digits and a number from 00-99 if the recording code has three. Data format: The letters ISRC, which are usually found printed with an ISRC on the item, should not be entered in field 016. Any ISRC which is found to be wrongly printed on the item can be entered in subfield $z, Erroneous ISRC, which is provided to give access to records that may have been requested by an erroneous number appearing on the item. Hyphens are inserted to separate the five parts of the number in the $a or $z subfield. No other punctuation is permitted. The purpose of the hyphens in the ISRC is to separate the distinct parts. When an ISRC is displayed in a catalogue entry the inclusion of the hyphens is mandatory. Many national agencies do not store the hyphens in the machine-readable record since they can be generated by algorithm if the range of publisher identifiers which have been allocated is known. When records are exchanged internationally the recipient of records may not always know the range of publisher identifiers. Therefore it is recommended that hyphens always be included in the ISRC in field 016 to ensure the display output. In order to distinguish between ISRCs when there is more than one in a record, qualifications may be added to one or more of them, according to the practice of the agency preparing the record. Terms of availability and price are often related to each ISRC. Thus this information is recorded in the same field. Punctuation is included with the data as required. The field should be repeated for each valid ISRC. It should be repeated for an invalid ISRC unless that invalid ISRC clearly relates to a known valid equivalent entered in the record, in which case the invalid ISRC will be entered in the same field as its corresponding valid ISRC. Some agencies may use the ISRC as record identifier and enter it in the field 001. In those cases the ISRC should be entered additionally in field 016.

Vocabulary for this indicator 0 Do not make a note 1 Make a note
Description	This field contains publisher's numbers used for sound recordings and publications of music.
Notes	The issue or label number is the number used to identify the issue designation or serial identification assigned by a publisher to a specific sound recording, to a side of a sound recording, to a performance on a sound recording, or to a group of sound recordings issued as a set. The issue number normally appears on the label and often on the packaging for these recordings. For a set of recordings there may be issue numbers on each disc and an additional set number on the packaging. The matrix number is used to identify the master from which the specific recording was pressed, usually appearing inscribed in the wax disc. It may be used for identification of a sound recording in the absence of an issue or label number. The plate number is a serial number assigned by a publisher to a specific music publication. It is usually printed at the bottom of each page of music and sometimes appears also on the title page. Other publishers' numbers are numbers similar to plate numbers but not appearing on each page of the publication. They may appear on the title page, the cover, and/or the first page of music.
