Title

¬An inquiry into the information retrieval efficiency of LISA PLUS database

Source

Malaysian journal of libarry and information science. 1(1996) no.1, S.67-84

Year

Abstract

Reports results of a study to compare the efficiency of the computerized searching of LISA Plus and Currents Research in Library and Information Science (CRLIS) with manual searching of the printed version of LISA. The study focused on articles covering the library and information science profession (LIS), published in Asian library and information science periodicals. The first stage was to identify Asian LIS periodicals using the Ulrich's Plus CD-ROM database. Computerized searching involved 2 methods; straightforward creation of sets for every periodical title; and browsing of brief citations of abstracts of all articles identified as being on the library profession published in the 1993 LISA. The manual searching involved browsing section 2.0 profession for all 11 issues of the printed LISA. Examines the reasons why computeroized searches took more time and retrieved less number of items. Suggests measures whereby the efficiency of computerized searches can be increased and concludes that to ensure comprehensive recall of relevant items, a combination of manual and computerized search is indispensible
