<<Because of the problem with the date change in the year 2000, we are having to redo our accession numbering. We've been accessioning by the last two digits of the date and then the order in which it is received, i.e., 97-1, 97-2, etc. 00-1 posses a problem for our system.>> Will your software allow you to add 2 extra digits? After 99-1, go on to 2000-1. If your software automatically inserts just the last two digits of the current year, then try setting up a prefix of "20". This will give you 20, then the last two digits of the current year, then your order number. You still get 2000-1. You just have to remember to change your prefix every 10 years.
