Using SGML Special Edition Deluxe

I have been researching moving SGML documents to the Web, and this book provided a comprehensive coverage of this topic. The authors lay out the various approaches to converting SGML to HTML and give the positive and negative aspects of each. Although the book is geared towards SGML/HTML implementations, it also gives a good description of SGML (in particular DTDs). I recommend Using SGML to anyone who needs to understand SGML and porting SGML documents to the Web.
