There are two ways to retrieve overdue information:
Go to "Circulation" and once there, select "library transactions"
Once in "library transactions", hover the cursor over "loans" and select "overdue loans all" (as shown in figure 1-1)
Another method is to run a report, either from "report wizard" or "new report module" (check the reports under the overdue category). This can be accessed by going to "reports" and you will see the options. Here is a link for more information to work with the new report module
