latex in Technology

language, text, tool
(Lamport TeX) Leslie Lamport's document preparation system built on top of TeX. LaTeX was developed at SRI International's Computer Science Laboratory and was built to resemble Scribe.
LaTeX adds commands to simplify typesetting and lets the user concentrate on the structure of the text rather than on formatting commands.
BibTeX is a LaTeX package for bibliographic citations.
Lamport's LaTeX book has an exemplary index listing every symbol, concept and example in the book. The index in the, now obsolete, first edition includes (on page 221) the mysterious entry "Gilkerson, Ellen, 221". The second edition (1994) has an entry for "infinite loop" instead.
