Explain please. Are you wanting to learn about investing or industries? What is it exactly that you don't understand? I've never seen a book about "industries," (but I haven't looked) although I'm sure there are one or two out there. But there are literally thousands of books about investing, and thousands more about trading.

From the NYSE - here are the industry sectors for the stock market

The Industry Classification Benchmark* (ICB) -- which comprises 10 industries, 18 supersectors, 40 sectors and 114 subsectors -- provides accurate and globally accepted industry and sector classifications.
