Free TeX and LaTeX Ebooks
TEX is a typesetting program, originally written by Prof. Knuth at Stanford around 1978. It implements a macro-driven typesetters’ programming language of some 300 basic operations and it has formed the core of many other desktop publishing (DTP) systems. Although it is still possible to write in the raw TEX language, you need to study it in depth, and you need to be able to write macros (subprograms) to perform even the simplest of repetitive tasks [Peter Flynn, 2005].
LaTeX is a user interface for TeX, designed by Leslie Lamaport at Digital Equipment Corporation (DEC) in 1985 to automate all the common tasks of document preparation. It provides a simple way for authors and typesetters to use the power of TEX without having to learn the underlying language. LaTeX is bundled with Metafonts, typesetting utilities and document formats. In Linux, TeX is distributed as teTeX and in windows TeX is distributed as MiKTeX. Another distribution of TeX is PDFTeX and it produces outputs in adobe acrobat format. They are many TeX IDEs around, my favorites being Kile, Kate and Kwrite.
