MarcEdit

An introduction to the MARC record editing software MarcEdit

Overview

While the Find and Replace function (among others) allows for global editing based on regular expressions, there are some more complicated regular expressions which are built into MarcEdit and which can be performed on fields within a record primarily to correct capitalization errors in a particular field or search for missing fields within a batch of records. These operations cannot be incorporated into an automation tool like a task or script. For more information on task management, see Task Management

Accessing Native Regular Expressions

  1. Open the .mrk file by selecting it in the folder, which should open the file in MarcEditor, or open MarcEditor from the MarcEdit home screen and select the file in File > Open.
  2. Each datafield will be indicated by “=XXX” notation, which is fully searchable within MarcEditor.
  3. Select Edit > Edit Shortcuts. Change Case and Field Edits should appear in the menu.
  4. If you highlight and click “Change Case,” you will be presented with the following options:

Find Records Missing Fields

This function allows users to search for records lacking a particular field, which is built in as a native regular expression in MarcEdit. It cannot be incorporated within an automated task.

  1. Once you have a document open in MarcEdit, select Edit > Edit Shortcuts > Field Edits > Find Records Missing Field as below:

                    

  1. The following dialog box should appear:

                                      

Based on the field and subfield data you enter here, MarcEdit will locate all records which are missing that field. Once you have entered the field click OK.

  1. Another dialog box will appear

                                 

The field and subfield data will be populated with your entry from the previous dialog box. If you click yes, MarcEdit will search for only records which are missing the particular subfield within the field specified. If you click no, it will search for the missing datafield regardless of subfields. This option will only be presented if a subfield is included as part of your entry in the previous step.

  1. Once you respond MarcEdit will perform the search. If it locates records missing the specified field, this results report will appear:

                                 

  1. From here you can highlight a record and click “Jump to Page” to edit or examine that record. You can also save this report by clicking on the yellow folder icon on the left hand corner or copy it to your clipboard by clicking the “copy” icon next to the folder. 

Limit Number of Fields

This function allows users to automatically limit how many of a particular field is present within each record. It will delete “from the bottom,” meaning that if there are three of a particular field in each record and this function is used to limit that field to one, the second and third will be deleted.

  1. Once you have a document open in MarcEdit, select Edit > Edit Shortcuts > Field Edits > Limit Number of Fields
  2. The following dialog box should appear

                        


Enter the field you would like followed by an equal sign then the number of fields you would like to limit. For example, if I wanted to limit the number of 500 fields to 1 I would enter 500=1.

  1. Click OK. MarcEdit will perform the operation. You can see the results of the operation given as an example in step 2 in the image below:

                                      

  1. To undo this action select Edit > Special Undo 

Swap Title

Allows users to take information from the 245$a field and copy it or move it into a separate field. This function can only be used on the 245 field. To swap other fields, see Editing Field Data.

  1. Once you have a document open in MarcEdit, select Edit > Edit Shortcuts > Field Edits > Swap Title.
  2. The following dialog box will appear

                       

Enter the field and subfield that you would like the material from the 245$a field to be copied too. This is designed to specifically swap the title field and will keep the data in the 245$a field in addition to placing into the copied field.

  1. When you have entered the new field, click OK.
  2. To undo this action select Edit > Special Undo
