Alan Hoenig's "TeX Unbound" is a very remarkable book which differs greatly from any other TeX-related book seen so far. This is not a book about using TeX or LaTeX; it is about related topics that are equally important to good typography, namely setting up and making proper use of PostScript fonts, and creating high-quality graphics illustrations with TeX-friendly methods.
The first five chapters provide a brief but comprehensive overview about TeX, LaTeX, METAFONT and METAPOST, with particular emphasis on how it all fits together, how the production cycle works, and what kinds of files are involved. While the material is generally adequate, it might be a little terse at times, and the coverage of recent TeX distributions and Internet resources is not quite as up-to-date as one might have wished.
The second part, comprising chapters 6--10, is one of the greatest strengths of "TeX Unbound" and delves deeply into the topic of fonts. Starting fr! om the basics of setting up a standard font family, it moves on to more and more fancy and extraordinary applications, covering a wealth of material you don't find anywhere else. For example, it explains how to generate special effects fonts, or how to set up a font family containing alternate character sets or symbols. This part is rounded off by a chapter on math fonts, followed by 30 pages of examples showing how various combinations of well-known text typefaces might be used together with the few choices of math fonts currently available.
Finally, the third part of _TeX Unbound_, comprising chapters 11--15, discusses graphics applications, with particular emphasis on TeX-friendly methods such as METAFONT and METAPOST, the PSTricks package, PicTeX, or MFpic.
If there is any other book that covers a similar range of topics as "TeX Unbound", it might be "The LaTeX Graphics Companion" which, however, sets different priorities.
In the area of fonts, &! quot;TeX Unbound" is clearly the winner. While "T! he LaTeX Graphics Companion" has a good coverage of the basics, "TeX Unbound" goes far beyond that, providing the deepest and most comprehensive coverage of the topic ever published so far.
In the area of graphics, both books are about equally good in their coverage of some of the best methods, but "The LaTeX Graphics Companion" covers a wider range of graphics applications, including quite a few methods you don't find in "TeX Unbound". Nevertheless, "TeX Unbound" provides enough to get you started.
In summary, "TeX Unbound" is a great resource if you like playing with fonts (and if you have a sufficient range of typefaces at your disposal). If your primary interest lies in designing graphics illustrations, "TeX Unbound<" does a good job of what it covers, but it is not the most comprehensive reference available.
