One book is not enough to help you clarify what you meant to write, try with more than one book. I am impressed by the amount of fonts needed in everyday life.

Yes, far more than one book. There are different classificatory systems. For example, Mrs. Eaves is a revival of Baskerville -- or maybe "inspired" by Baskerville? So, is it "digital" or "transitional" in your system? The three you term "old style" I would break into different categories, with, for example, Bembo being a Venetian.

People classify fonts for varying reasons, so no one system is right or wrong.

The FontBook categories are Sans, Serif, Script, Slab, Display, Blackletter.

It also gives the name of the designer/redesigner, date of design, and "similar to" links.

It is not comprehensive, as some foundries are not included.

What I’am trying to say, I’am not able all the time to categorise a font, and a book who tell me this font is a modern font etc. are going to help me.

There's no book out there that can be considered a definitive resource for font classification. Classification systems are very much a subject of debate, as is which typefaces go where, so it's really up to you to nitpick for yourself.

Rookledge’s Classic International Typefinder – btw a good source for identifying older typefaces – breaks down into categories based on BS 2961 (in turn based on the Vox system). Not perfect but a starting place.

Good answers so far. Classification is very subjective and there is no comprehensive volume of all available typefaces. FontBook is just the most comprehensive.

What may help you is the greatly expanded "See Also" cross references that relate similar fonts.

Thanks guys for responding.
