Basic MARC field explanation

Basic MARC field explanation

This document is intended for the casual copy cataloger, focusing on the physical book. For a comprehensive list of MARC fields, see the following resources.

Resources:

  1. Bibliographic Formats and Standards - OCLC 
  2. MARC 21 Format for Bibliographic Data: Table of Contents (Network Development and MARC Standards Office, Library of Congress) 
The bibliographic record describes the item in hand (book, CD, DVD, eBook, map, etc.). to describe the item, we use the MARC21 standard. The MARC21 standard divides the MARC record into fixed and variable fields, denoted by three-digit numbers. Fixed fields and variable fields encompass the bibliographic record.  

Indicators: Each MARC field has two indicators, the first and second. Depending on the system, blank indicators can be represented as a blank or #. If not left blank, indicators are numbers.  

Subfields: Subfields divide MARC fields into more specific sections. Depending on the MARC field, subfields can be letters or numbers. Subfields will be represented by symbols $, $$, †, or ‡, depending on the system.

Minimum Requirements for MARC Records

Fixed Fields

Fixed Fields are represented in the bibliographic record by field LDR and 008.

Check the date (should be the same as the publication date on the item and in the 26x field) in the 008. The date appears seven characters from the start of the line.

Variable Fields

0XX Control Fields

020: This is the ISBN field. There is likely to be more than one of these fields, as books often have multiple  ISBNs. Note that this field is only for books. DVDs may have a 024 field, or they may not.  


042: Records with a 042 MARC field are a good record to use; those records are PCC records (Program for Cooperative Cataloging) and are considered good records by MnPALS catalogers. 

 

035: OCLC number field. Additionally, Alma stores other system numbers in MARC field 035. The OCLC number is a unique number assigned to the record. OCLC will merge duplicate records, in which case, there will be multiple OCLC numbers. In Alma, these numbers may take several forms: (OCoLC)123456, ocm123456, ocn123456, 123456, etc. If a record has multiple OCLC numbers, you can search OCLC using any of the numbers. 

Call Numbers

Physical records must have a call number in 050 Library of Congress or 082 Dewey.

050 Field: This is where the Library of Congress (LC) call number goes. The LC call number starts with letters. The call number has two subfields–$a and $b. Subfield $a is the classification number, and subfield $b is the Cutter number, usually ending with the publication year.   

082 Field: This is where the Dewey Decimal call number goes. The Dewey Decimal number starts with three numbers. The call number has two subfields–$a and $b. Subfield $a is the classification number, and subfield $b is the Cutter number.


Main Entry, 1XX

Record the author in field 100. Additionally, you may see 110, corporate name, or 111, a conference name.

100 Field:  This is the author field. Not every record will have a 100, for instance, if a book has an editor but not an author.  

 

  1. Verify that the author listed on the title page matches the author in the bibliographic record.
  2. If there are two or three authors, the first author listed is in the 100; additional authors should be listed in field 700.

Example:

100 10 $a Lovelace, Maud Hart, $d 1892-1980. 
 

Titles, 24x

 245 field:

The 245 is the title field, and every bibliographic record must have a title, 245 field. It will generally also list the author in subfield c. The first indicator is 1 if there is a 100 field in the record or 0 if no author in field 100. The second indicator indicates the number of non-filing characters. Non-filing characters are words at the beginning of the title that the system ignores for sorting purposes. In English, these words are: a, an, the. Corresponding words in other languages also have non-filing characters. The number of nonfiling characters will depend on which of these words starts the title, and adds one more value to represent the space between that word and the next. The word “The” is 4, “an” is 3, and “a” is 2. (However, if a title begins with a quotation mark, that adds another non-filing character.) If the title does not start with one of these words, then the second indicator is 0.

  1.  Verify that the title in the 245 matches the title on the title page.

 Example:

 245 10 |a Betsy and Tacy go downtown / |c Maud Hart Lovelace ; illustrated by Lois Lenski. 


Edition Statement

250 Field:
This is the edition field. That information will be listed based on whether the book is a first, second edition, etc..

  1.  Verify the edition statement on the item, for example, 2nd ed., Rev. ed.

 Example: 250__ |a 1st Harper trophy ed. 

Publication information 26X 

 260 or 264 Field:

These fields provide information about publication information. 260 is an older form of the field, still present in some older records. 264 is the newer version of the field. 260 and 264 have the same subfields: $a, $b, and $c.

 

$a is the city of publication.

$b is the name of the publisher.

$c is the date of publication.

 

Records with a 264 field may contain a second 264 field containing the copyright date.   

  1.  Verify publication information from the title page and/or title page verso. Ensure the publication date is consistent with the fixed Dates (008).

Examples:
      260   |a New York : |b Harper & Row, |c 1979. 
      264 1|a Washington : |b U.S. Government Printing Office, |c 2024

Physical Description 3XX

 300 Field:

 This field provides physical details about the resource.

$a provides the number of pages.

$b illustrations (charts, tables, drawings, photographs, etc.).

$c provides the dimensions (usually just the height, in centimeters).  

  1.  Verify the paging and illustrations of the item on hand. For books without pages, the 300 field will look like – 1 volume or 26 unnumbered pages. Fixed Ills field must reflect information in |b. 
  1. Example: 300 __|a 180 pages : |b illustrations ; |c 20 cm. 

 

Each record should contain fields 336, 337, and 338.

Example for books:

 

336  |a text |2 rdacontent
337  |a unmediated |2 rdamedia
338  |a volume |2 rdacarrier 

Series statement 4XX and/or 8XX

490 Field:  This field is for the series statement. Newer records will also include the authorized (traced) form of the series in an 830 field (the authorized form of the series in the 830 field may or may not be worded differently than the name of the series in the 490 field).   

Verify the series with the item on hand. 

 

Example: 490 0_ |a A Harper trophy book.

8xx: Series added Entries, maybe represented in fields 800, 810, 811, or 830.

Verify an 8XX field exists if 490 1_  is used 

 

Example: 800 1_|a Lovelace, Maud Hart, |d 1892-1980. |t Betsy-Tacy book ; |v 4.


Note fields 5XX

5XX Fields:  Fields in the 500-599 range are note fields. Records may or may not include 5XX fields. Some common note fields are:

 

500 general notes 

505 table of contents 

520 summaries 

59X are Alma reserved local notes, appearing in IZ only. 

 

Examples:

500 __|a Originally published under the title: Down town, a Betsy-Tacy story.

The first indicator will be blank for all these fields, and the second one should be 0, indicating the subject heading comes from the Library of Congress Authority File. There can be other values in 6XX fields beyond Library of Congress subject headings in the second indicator. Any subject field may have several subfields to subdivide topics further.    

Example:

650_0 |a City and town life |v Juvenile fiction.

651 _0 |a Minnesota |v Juvenile fiction.
