Abstract
This short guide is intended to help librarians and OPAC system designers to make decisions about the design of displays of more than one subject heading. The authors stress that they offer guidance rather than standards or prescriptions; their clear prose is cautious and even the number of recommendations is limited. A 12-page introduction contrasts the "structural approach" and "strict alphabetical approach" to filing, showing examples and stating arguments for each. 7 chapters cover display of subdivisions, inverted headings, display of qualified headings, arrangement of numerical headings, display of subjects interfiled with names and titles, punctuation and messages to the user. Within each chapter, questions involving choices between two or more approaches are followed by brief statements of current practice (LC rules, ALA rules, and systems in existing OPACs) extensive examples demonstrating such choices, and arguments for and against each. The authors warn against ever assuming that the user knows the needed subject headings, and acknowledge that the best OPAC design often depends on the setting and on the user's understanding of the system. Although the topic may be beyond the purview of the authoring committee, the discussion here makes one yearn for interactive OPACs that can analyze the user's needs and provide appropriate guidance to whatever system is adopted
