Is there a limit as to how many rares (from different races) you can work on at a time?
I'm being paranoid, but Archaeology IMO is a pain of a profession and I'd hate to see my NE fragments go to waste trying to get that rare I want when I have a rare from the Dwarven branch in Archaeology that I've yet to solve due to a restriction which states that you can work on one rare at a time.
I guess what I'm asking for is confirmation that you can work on two or more rares at the same time.
