I don't think I have seen an encyclopedia for well over 20 years now.
I read articles (and in my former life, books), lots and lots of articles. For this topic? Wikipedia? for real?
I looked into selling encyclopedias in the '80s after my divorce as a source of exta income. Income halved costs doubled so I was looking for any alternative for extra money.
I have had several sets throughout my live (but long since given them away) including: World Book, Grolier, Britannica.
The truth of the matter is the Britannica was an antique set that in retrospect I wish I had kept as I have never seen another like it and it had stuff in it that you wouldn't find in newer versions.
