"Typesetting" is the rendering of letterforms on visible media. Examples are the words (not the graphics) on the printed pages of a book, or the words on the display of your computer screen. Software for typesetting covers a broad range: software appropriate for typesetting a phone book will be of little help in preparing a magazine. Also, it is frequently difficult to separate the "software" from the "system," so this category will include proprietary typesetting systems. One can't set type without fonts, so we will address fonts here. We will also provide links to related technologies and information such as digital type design and research on human perception of type.
