Title
Subject enhancements and OPACs : planning ahead

Abstract
As librarians plan ahead to make subject enhancements available to online searchers in various possible file locations and formats, they may want to base their decisions on implications for online searching. This paper explores some of these implications with respect to unique and misleading terminology in tables of contents, Choice abstracts, and reviews from Computing reviews for thirty-six books on information and computer science chosen from the 1987 issues of Choice. It also discusses possible interacting functions in the search process served by these subject enhancements, assigned LCSH, and book title terminology
