Tib is a collection of four programs for making citations and reference lists in TeX documents. The main program, Tib, operates on a TeX file with incomplete or keyed citations, looks up the reference in a database, makes the complete citation and on command, makes a list of the references. The citations in the source document are enclosed in (non-TeX) escape characters which Tib recognizes. The output of Tib is another TeX file with complete citations and reference list formatted with a number of TeX control sequences and with definitions for these control sequences, ready to be processed by Plain TeX, LaTeX, or whatever.
