 There are times when you need to work on a subset of your MARC data. The Select Records for Edit function allows you do this.
 
+Before using the Select Records for Edit function, save your file to capture recent edits.
+
 Go to File and click on Select Records for Edit. In the window, you will see Display Field in the lower right hand corner. This is where you enter the MARC field you want to see displayed once you import your file. You can enter a MARC field and subfield or just a MARC field. The MARC field and/or subfield that you add in this box will provide the criteria you need to select records you want to edit. Once you have entered the Display Field, click on Import File. This will import the MARC (`.mrk`) file that you are currently working on. You can select another MARC (`.mrk`) file in the box Source MARC file.
