Not sure if this has been posted before. I did a search but couldn't find anything.

Anyway I have just started reorganizing my entire stamp collection and started with my Canada collection.
Canada Post released stamps for various series over an extended number of years such as the Lunar New Year or Art Canada stamps. In the Unitrade catalogue they are listed as Lunar New Year - 2 or Art Canada - 5 etc.
Do you as a collector keep the series together as a set? such as organizing the entire Lunar New Year or do you keep them separate and the set would only be the stamps that were issued as part of that year's issue?
Hopefully my question is clear...I can try to clarify if you don't understand.
