| contents | Three Library and Information Science Databases Revisited: Currency, Coverage and Overlap, Interindexing Consistency. Blackwell, Michael Lind Abstracting Abstracts Access to Information Citation Indexes Comparative Analysis Database Producers Databases Indexing Information Retrieval Information Science Periodicals Scholarly Journals User Needs (Information) This study evaluates the "Education Resources Information Center" (ERIC), "Library and Information Science Abstracts" (LISA), and "Library Literature" (LL) databases, determining how long the databases take to enter records (indexing delay), how much duplication of effort exists among the three databases (indexing overlap), and how consistently the databases index materials (interindexing consistency). The study employed the methodology of studies on the databases from the 1980s, yet also used measurements based on methodologies not previously. The findings were compared with findings from earlier studies in order to discover indexing trends in the databases, and it was revealed that, over the last 25 years, indexing currency has generally improved, overlap has increased, and joint coverage has remained relatively stable. It was also found that the three databases together cover only 44% of all possible titles. Recommendations are offered to the users and producers of the databases. Data is presented in 11 tables, and 4 appendices provide a list of library serials, a core list of essential journals, a list of serials covered, and core journal names. (Contains 15 references.)
