| Summary: | Tests the information retrieval efficiency oj LISA Plus database in retrieving the
abstracts oj articles on the library projession published in Asian library and
information science journals jrom the ajorementioned database by employing two different
methods oj computerised searches and a manual search. The manual search
from LISA (printed version oj LISA Plus) retrieved 73 articles in 26 minutes, whereas
the computerised searches retrieved 42 and 19 articles in 90 and 41 minutes
respectively. Examines the reasons why computerized searches took more time and
retrieved less number oj items. Suggests measures whereby the efficiency oj computerised
searches can be increased and concludes that to ensure comprehensive recall
of relevant items, a combination ojmanual and computerised search is indispensable. |
