The SGML FAQ book

Drawing on many years of work with SGML systems, DTD's and users, Steve DeRose has assembled The SGML FAQ Book, which addresses the questions SGML users of all kinds run into in their daily work (from the Web author to the high-tech documentation specialist). In a clear, accessible style this book provides the answers to those questions, as well as recommendations on how to use SGML most effectively.

The questions are organized by kinds of SGML users, ranging from authors using systems that (usually!) hide most SGML details, to authors who deal directly with SGML, to DTD designers and others who get into all the gory details.
