You can edit these elements of a MARC record:
• | Tags. The tag is the three‑digit number associated with each field. You can change or add tags in a MARC record. |
Fixed fields are also called “controlled text.” Make sure that you understand MARC standards before you make any changes in fixed fields. (For more information, see Library of Congress publications about MARC, or visit the Library of Congress web site at http://lcweb.loc.gov/marc/.)
• | Indicators. Horizon displays an undefined indicator as an underscore ( _ ). You can edit an indicator by replacing it with a lowercase alphanumeric character or by deleting the existing character. Make sure that you understand MARC standards before you make any changes in indicators. (For more information, see Library of Congress publications about MARC, or visit the Library of Congress web site at http://lcweb.loc.gov/marc/.) |
If you have error checking turned on, double-clicking on an error message positions your cursor in the record at the error so that you can correct it easily. (For more information, see Activating Error Checking in Records.)
You can use SHIFT+F1 from a valid MARC tag in a MARC record to link directly to the Library of Congress web site where that tag is explained. Your system administrator can change the link so that it finds a different URL. (For instructions, see “Setting Up or Changing Valid MARC Record Components” in the
To edit components of a MARC record
1 | Open a MARC record. |
2 | Do one of these options: |
• | Put your insertion pointer on the left side of the component where you want to enter information. |
• | Highlight the information that you want to change. |
3 | Enter the new information for that component. |
Note: When you have your insertion pointer in a component marker (such as a tag, indicator, or subfield delimiter) or in any other component that has valid values defined, you can press F12 for a list of valid codes. Double‑clicking on the code that you want inserts it into the proper position. (Horizon notifies you if no valid codes are available.)
