Query: This is supposed to be what?

The book title is a bit deceiving. The cover does say, "Standard Encyclopedia of Carnival Glass". What part of 'encyclopedia' did I miss? This is nothing more than cheap paper with a long list of designs. If you ever hope to identify anything, this is not the book for you. Personally, I thought an 'encyclopedia' might help me identify, but not a single picture. My book now resides at the paper recycling dump. It really is that worthless.
