研究了在线公共检索目录（OPAC）系统中两种主题表示模式——目录（TOC）和主题标题（title）在主题检索中的有效性。TOC与美国国会图书馆主题词（LCSH）的检索差异有统计学意义；学科领域的影响无统计学意义；用户将关键词与TOC匹配的成功率高于LCSH；但他们的关键词往往无法检索到与目标物品相似的物品。这些发现强调了将用户关键字与TOC和LCSH连接起来的必要性。
The effectiveness of two modes of subject representation - table of contents (TOC) and subject headings - in subject searching in an online public access catalog (OPAC) system was investigated. The retrieval difference between TOC and the Library of Congress subject headings (LCSH) was statistically significant; the effect of subject domain was not statistically significant; users had better success matching their keywords to TOC than to LCSH; but their keywords often failed to retrieve items similar to the target items. These findings underscore the need to bridge user keywords to both TOC and LCSH.
