It stands for the launch list which is a separate list that highlights some of the recent products on the Product Library. The cost to enlist your product is $20. You do not have to use that list in order to have your product in the Product Library. The Product Library itself is still free to use.
The consumer product library is a separate list (from the Product Library) which lists the latest released products. Once listed you can also bump your product back to the top of that list at a later time.
