Books that impart information and data MUST have a comprehensive TOC and index section, otherwise they're less useful as a reference source.
I'm not sure how widespread this remains, but many factory repair manuals did not contain an index. Unbelievable. And they wonder why their techs never/seldom use them. BTW, ever try to find some information in the Porsche manuals? I haven't seen the latest ones, but the big buck, multi-volume sets for the 911 are in the above category. Great info, poor format.
