We had a carry forward item on this MRD. It required an inspection every 7 days. The last line of the carry forward entry indicated that the item had to be repaired by XA/31/XX (which is a separate issue). We flew on XB/14/XX. According to the MRD; the plane is grounded for failure to repair the item according to the FAR.Upon inquiry to [Maintenance Control]; we discovered that the completion date had been changed to XC/31/XX (again; a nonexistent date). The writeup on the MRD however showed no such thing. It turns out that only seven separate items can be entered under a carry forward item number. This item therefore had an unknown number of entries which were not available to the cockpit. While [Maintenance Control] can see the entire paper trail; the crew cannot. This is unacceptable. At the very least; the latest entries regarding a maintenance item must be available to the crew. Preferably; ALL entries should be available to the crew.This is a failure of the MRD format.
