| Summary: | 碩士 === 淡江大學 === 教育資料科學學系 === 83 === The main purpose of theis study is to find out the difficult-
ies of the users when using Chinese Online Public Access
Catalog (OPAC). This study is based on questionnaires,
interviews and per- sonal observation. Samples are collected
from OPAC systems of Chengchi University Library and Tamkang
University Library. Descriptive statistical methods as well as
content analysis are applied in summarizing and evaluating the
data. By analyzing the users'' searching behavior and the
problems which they encountered when interacting with the OPAC
systems, the researcher identifies ten types of difficulties,
namely: (1) Users'' unfamiliarity with keyboard operation; (2)
Users'' lack of training in Chinese input skill, and mode switch
between Chinese and English; (3) unintelligible the information
system responsed at times; (4) Users'' inability to utilize
access points and function keys; (5) insufficient cross
reference amount related subjects and proximate subjects; (6)
Users'' inappropriate choice of terms for keyword search; (7)
improper division of search terms (斷詞) by users; (8)
insufficient further infor- mation about the searching result;
(9) the holding status of the items need to be updated more
frequently; (10) new equipment should be acquired, and system
data should be enhanced. The other findings are as follows: the
major access points of the users are subject (61.80%), title
(53.93%), author (47.19% ). The results also reveal that the
users'' major difficult area is the subject keywords. The major
factors affecting users'' satisfaction in the process of
searching seem to be the users unfamiliarity with the
operational functions and the limitation on the online help
function of the systems.
