TeXsis is a TeX macro package which provides useful features for typesetting research papers and related documents. For example, it includes support specifically for:

• automatic numbering of equations, figures, tables and references;

• simplified control of type sizes, line spacing, footnotes, running headlines and footlines, and tables of contents, figures and tables;

• specialized document formats for research papers, preprints and e-prints, conference proceedings, theses, books, referee reports, letters, and memoranda;

• simplified means of constructing an index for a book or thesis;

• easy to use double column formatting;

• specialized environments for lists, theorems and proofs, centered or non-justified text, and listing computer code;

• specialized macros for easily constructing ruled tables.

TeXsis was originally developed for physicists, but others may also find it useful. It is completely compatible with Plain TeX.
