Import contacts into global Address Book

We just migrated from NetWare and GroupWise to Win2k and Exchange 2K. I’ve exported all the entries in a shared GW address book to a CSV file. I would like to know if there is a method to import these contacts to the Global Outlook Address Book, as these are contacts all our users would like access to. I’m completely new to the Win2k environment, so any help would be greatly appreciated.
