How do I extract MARC records from a file using MarcEdit

  •  I have a file of records, I want to extract specific a specific record or a subset of records from the file.  
  •   If they have the ISBN/ISSN/OCLC Numbers or the titles of the records they want to extract they can use MARCedit to search large files, batch select the specific records, and send them to a separate file.
Applies to
  • WorldCat Collection Manager

If you have the ISBN/ISSN/OCLC Numbers or the titles of the records you want to extract you can use MarcEdit to search the files, batch select the specific records and send them to a separate file.


1.  Create an Excel file that contains information about the titles you are seeking*

3   Import the file of records into MarcEdit** 

4. Import the Excel sheet of titles to run against the .mrc file.  Extract just those matched records to a file.  MarcEdit may default to a .mrk file,  we recommend changing this to a     .mrc file. 

*Create a text file that contains the search strings that you wish to use to select these records.  The file should have one search string per line (no arrow brackets):
