Cigarcyclopedia is fantastic. Old brand history, new brands, blends, manufacturers, size trends, what more can you ask for.
Can often be found on CigarBid or as a freebie from Mike's in Miami.
Can be bought direct from
cigarcyclopedia.com.
I love looking at the old ones I have, they're worth saving.
Lots of current info on line as well. The comparison shopper is great to help find the lowest prices. Cigar news updated almost daily. Check it out.
PS- I'm not associated with this site, but I wish I was! It's that good.
