For example, the boxed entry in the list for 2001 above, gives 003-18FEB. The 003 is the third Infoline to be published and it came out on 18-FEBRUARY-2001.
There is a variation to this system and that is when a special (out of normal sequence) Infoline is published. The number of the Infoline has the first two characters as the number of the Infoline and the third character is the letter S. The day and month remain the same as a standard Infoline. You can see the first infoline special under the year 2003 as a boxed entry. It reads 01S-21MAR.
