Trading Cards Sets List
I also collect traditional "trading card sets". There are to many sets so I've dedided to concentrate only on some of them.
If you want to find a specific set just buy "The Encyclopedia of Non-sport & Entertainment Trading Cards". If you want to see a great site with all the checklists of all the sets please visit Jeff Allender's site.
I've also found somewhere this useful list of definitions.
I've started to collect all the "widevision format" sets, then all the "chromium/metal/holofoil" ones and all the "mega cards" ones. I collect only the basic set without chase, foil or promo.
