Project Gutenberg is an electronic collection of documents and literature, the majority of which exist in ASCII format. While the ASCII format has been an almost universally accessible format since the Project started in 1971, the possibilities and advantages of marking up the texts with the Extensible Markup Language (XML) are compelling.

The prepared DTD provides the schema against which 5 test documents are marked up with XML. A tutorial based on my experiences marking up the text and an index of the available elements are included
