### Books on TeX and its relations

There's a nicely-presented list of of "recommended books" to be had on the web: http://www.macrotex.net/texbooks/

The list of Metafont books is rather short:

The Metafontbook
  by Donald Knuth (Addison Wesley, 1986, ISBN 0-201-13445-4, ISBN 0-201-52983-1 paperback)

Alan Hoenig's 'TeX Unbound' includes some discussion and examples of using Metafont.

A book covering a wide range of topics (including installation and maintenance) is:

Making TeX Work
  by Norman Walsh (O'Reilly and Associates, Inc, 1994, ISBN 1-56592-051-1)

The book is decidedly dated, and is now out of print, but a copy is available via `sourceforge` and on CTAN, and we list it under "tutorials".

This list only covers books in English: notices of new books, or warnings that books are now out of print are always welcome. However, this FAQ does not carry reviews of current published material.
