Python script to fix MARC21 indicators in batch records

[melzalabany]

Summary

Create a Python script to fix MARC21 indicators in batch-processed records.

Details

• The script processes a file containing MARC21 records in standard format.
• For each tag with indicators, ensures there are exactly two indicators after the 3-digit tag (pads with spaces if missing or incomplete).
• Fields that do not use indicators (such as =LDR, =001, =005, =008) remain unchanged.
• Output is a corrected version of the MARC file, suitable for use with migration tools.
• Example input and output provided in the discussion.

Example usage

1. Save MARC records to marc_records.txt.
2. Run the script: python fix_marc_indicators.py
3. Output is saved as marc_records_fixed.txt with corrected indicators.

Implementation

The script uses regex to identify and fix indicators. See user prompt for example input data and further details.

@banerjek Would this be a better candidate for marcfix?
