The Reporter Dictionary is a flat table that defines categories for cataloguing Library cards created by staff when they name and save them in the Reporter. The next screen shot shows where in the Reporter these MasterCodes drive the drop down menu selections for the Program field when a Library card is added or edited in the AMS. 
Some associations choose to catalog Library cards by the departments that run the queries, while others catalog them by the contact group for which they are being built. For example, there could be a Library card that lets you know which members have made donations. This card could be catalogued under “Membership” or “Fund Raising”.
Your association has to decide how to catalog your Library cards, and you can create any MasterCodes you need for this purpose in the Reporter Dictionary, which is seen at the NR2 GroupType level in the next screen shot.
NR2 is the only GroupType in the Reporter Dictionary, and its only GroupCode is expanded to display multiple examples of MasterCodes.
The entire process for creating and editing Library cards is covered in the Reporter section of this knowledge base.
