Fields & Tags:

Each bibliographic MARC record is divided into fields. There is a field for the author, a field for the title information, and so on. Each field is marked by a 3-digit tag. For example, the number 100 is a tag which marks the personal name main entry (author) field:

	100 1   Chute, Marchette Gaylord, 1909- 

Some tags are more frequently used than others. In the MARC 21 standard, only a small percentage of the tags are used over and over. Go to the next page to see the most frequently used MARC 21 tags. It is highly recommended that you memorize each tag with its related field.
