LaTeX is an open-source, free typesetting system for producing beautiful books. It is available for almost every operating system, and is a stable, mature product with a large user base. With it, you can make camera-ready pdf’s of books and theses, plus other documents of many kinds. It has too many features to name in a short description, and in power it is closer to a desktop publishing system than to a word processor. BibTeX is a bibliography database management system designed to work with LaTeX. It is similar in power to Endnote and Zoho. MakeIndex is a utility for making complex, multi-level indexes (indices?). It is designed to work with LaTeX, but can also be used to organize an index you prepare from galleys.
