TEI: P4 Guidelines
The TEI P4 Guidelines first appeared in print in June 2002. P4 was the first version of the Guidelines to implement proper XML support, while ensuring backwards compatibility with earlier TEI specifications.
Getting the P4 Guidelines
The TEI Guidelines are also provided as a modular, extensible, DTD (Document Type Definition). The modules making up the TEI DTD can be configured for use either as an SGML or an XML DTD. There are full details in the P4 DTD document.
The P4 Guidelines were published by the University of Virginia Press. Remaining copies will be available until 31 December 2012, at the price of $US14 plus shipping ($6 to United States addresses; $17 to other countries).
