There are new discoveries all the time. There's no way anyone could know it all. Look at how many globes were discovered between the first and second globe books. I think the 1993 book listed about 3000 different globes. The 1999 version about 5000 globes! I doubt if there will be that kind of increase when the next globe book is written, but there have been alot of new discoveries since '99.
