- Abstract
- Knowledge tends to be structured differently in different types of information resources and information genres due to the different purposes of the resource/genre, and the characteristics of the media or format of the resource. This study investigates subject organization in three types of information resources: books (i.e. monographs), Web directories and information websites that provide information on particular subjects. Twelve subjects (topics) were selected in the areas of science, arts/humanities and social science, and two books, two Web directories and two information websites were sampled for each subject. The top two levels of the hierarchical subject organization in each resource were harvested and analyzed. Books have the highest proportion of general subject categories (e.g. history, theory and definition) and process categories (indicating step-by-step instructions). Information websites have the highest proportion of target user categories and genre-specific categories (e.g. about us and contact us), whereas Web directories have the highest proportion of specialty categories (i.e. sub-disciplines), industry-role categories (e.g. stores, schools and associations) and format categories (e.g. books, blogs and videos). Some disciplinary differences were also identified.

- Abstract
- The Online Public Access Catalog (OPAC) is an information retrieval system characterized by short bibliographic records, mainly of books, journals, and audiovisual materials available in a particular library. This, coupled with a Boolean search interface and a heterogeneous user population with diverse needs, presents special problems for subject searching by end users. To perform effective subject searching in the OPAC system requires a wide range of knowledge and skills. Various approaches to improving the OPAC design for subject searching have been proposed and are reviewed in this entry. The trend toward Web-based OPAC interfaces and the developments in Internet and digital library technologies present fresh opportunities for enhancing the effectiveness of the OPAC system for subject searching.
