Hi David

This is undocumented command by cisco .

This command shows you the lsas which have been deleted from
consideration. as i don't have ospf running, i can't ascertain whether
this is lsas which were taken out of consideration by the SPF algorithm
or by other means.

ctalkb#sh ip ospf delet
AS System N

    Area BACKBONE(0)

    ROUTER and NETWORK LSDB delete list

      Dest: 172.16.0.1, Type: 0, Metric: 1, ADV RTR: 172.16.0.1
      Path:
        gateway 172.16.0.1, interface Loopback0

    SUMMARY NET and ASBR LSDB delete list

Hi David,

Yes, it is a hidden command. "de" is short for delete-list.

show ip ospf delete-list

It is documented here:
