Industry & Company Information: Books

Start here for all your industry information needs.

Reference Books

Intended for a quick check of basic company information, directories have a listing by industrial classification code that can be useful in estimating how many companies operate in the same or a related industry.


Ratio Books

These sources give standard financial ratios (e.g. debt to equity, return on investment, and more) used for centuries as benchmarks for comparisons of company performance to the rest of the industry.  What you see is what you get!  They do not cover all industries, favoring manufacturing over retail, for example.  They do not cover industries that generate little revenue (e.g. pencil manufacturers).  Data about industry subgroups (e.g. car mufflers) will be embedded in entries about the larger industry (e.g. after-market auto parts).

Industry Analysis and Ratios of Leading Companies 

These sources comment on critical factors for analysis such as the structure in various industries, market drivers, consumer behavior, and what numerical and qualitative information are important in analyzing that industry.  They also give ratios for key industry competitors.
