Mathematica notebooks include all the usual features of a top-quality word-processing system, plus many additional special capabilities. In all, there are over a thousand formatting and styling options, all accessible both from menus and at a programmatic level. Mathematica notebooks have an underlying symbolic structure that allows full markup, cascading stylesheets, and the ability to immediately restyle a document. Notebooks can be optimized not only for interactive use, but also for export to web and print media.
