对美国及加拿大高校图书馆数据库的利用数据进行随机抽样，揭示出所抽查的各类型图书馆数据库的利用模式。图书馆用户倾向于利用商务联机数据库，最频繁利用的时间是在周初、中午及与高校作息时间相一致的时间（抽样调查时间为期６个月的１１月份）。按平均数计算，在任何规模的图书馆里同时登录研究型数据库的用户相对较少。调查表发放到抽样图书馆，调查可能影响数据库利用的因素，包括教育水准、远程登录的可用性及图书馆主页上数据库的布置，统计结果未发现任何重要因素。
The random sampling of the utilization data of the university library database in the United States and Canada reveals the utilization patterns of the various types of library databases searched. Library users tend to use business online databases, most frequently in weeks, noon, and hours of work in the university (sampling period of 6 months in November). On average, there are relatively few users logging into a research database at any one time in any size library. The questionnaire was sent to the sampling library to investigate factors that may affect the utilization of the database, including education level, availability of remote login and database layout on the library home page. No significant factors were found in the statistical results.
