Library of Congress >> MARC >> Understanding MARC MARC 21 Reference Materials Part XI: A Sample Record in Various Formats Part XI:A Sample Record in Various Formats A note on the sample records shown here. Here are examples of the same bibliographic record in various formats. MARC 21 communications format: The block of data below is what the programmer sees when he looks at the contents of a MARC file. The tags do not appear before the fields, but a directory to the data tells which tags should be used and where each field starts (in other words, where each tag belongs).
Cracking the code, or, Interpreting the directory: Usually, only the computer programmer and the computer come into contact with the record in MARC 21 communications format, but it is interesting to understand how the directory works. The first 24 positions are the leader. In this example the leader fills approximately 1/3 of the first line and ends with "4500." Immediately following the leader, the directory begins. Tags have been underlined in this example. Each individual tag directory is 12 characters long. The first tag is 001. Following each tag, the next four positions show the length of the field. The data in the 001 field (control number) in this record is 20 characters long. The next 5 positions tell the starting point for this field within the data string that follows the directory. The 001 field begins at the 00000 position (the first position is position 0). The next tag is 003, which is 4 characters long and begins at the 20th position (the length of the previous position -- 20 -- added to its starting spot -- 00000 -- equals 20). The next tag is 005. It is 17 characters long and begins at the 24th spot (4 + 20 = 24). This directory tells us:
Field terminators (displayed as a ^ in this example) mark the end of the directory and the end of each field that follows. Notice that the sum of the 2nd and 3rd column in any row equals the number in the 3rd column in the next row. The starting point of one field plus its length equals the starting position of the next field. This can be verified by counting the character positions within the data, remember that spaces count, as do the field terminators (^). (Two character positions are always reserved for indicators at the beginning of a field.) A record terminator (displayed as a \ in this example) ends each bibliographic record. Tagged display: Most data editing screens are called "tagged displays" because they show the MARC 21 tags, inserted where they belong, as directed by the directory. A computer program has been written to do this tagging. The example below, a sample data entry screen, is tagged. Sample Local

Formatted displays: The type of screens OPAC patrons use are formatted, since MARC tags would be meaningless to the general public. Within each particular OPAC program is a routine that formats each record in the way the designers thought would best serve the public using the online catalog. A similar transformation takes place if catalog cards are printed from a MARC record, as illustrated in the 3rd example. Sample of a brief record display as seen by a patron:

Part XII:AV Records: From Cards to MARC 21Book vs. non-book: Audiovisual materials are cataloged following many of the same rules as for books (from AACR2) and tagged using many of the same MARC 21 content designators (from the MARC 21 Format for Bibliographic Data). The differences from book tagging could be summarized as follows:
Remember: For complete details about the 007, 008, and any special tags
used with audiovisual materials, see the MARC 21 Format for Bibliographic
Data. Examples: On the following pages are examples of cataloging for three types of non-book items. These pages show how the data on catalog cards would appear, then how the same record would be tagged with MARC 21 content designators. Additional examples may be seen in several of the resources cited in the bibliography . Typical videorecording in card format:
