Marti Heyman and Pilar Wyman, co-chairs of the NISO Z39.4 Working Group, will talk about the current state of development of a proposed new NISO indexing standard. They will relate how the working group came to be, the NISO standards process, and the intellectual work involved in using the 1997 technical report as the foundation for reestablishing a standard. Besides advances in technology, another challenge has been finding the language and articulating the common ground and connections between open and closed indexing. Sound familiar? Vocabulary control is ever the name of the game, indeed.
