A little more than 30% of the respondents answered that they used the NDL website “More than once a month,” and nearly 60% of the respondents answered “More than once a week.” Compared with the previous survey, the percentage of “More than once a month” and “More than once a week” has increased. Overwhelming majority of the respondents uses it to “Use online catalogs,” “Request copying services” and “Request ILL services.” Other purpose frequently cited is for “Reference work.” This shows the same tendency as the previous survey.

More than 50% of the respondents use the copying service by postal mail “More than once a year,” and more than 20% of the respondents use it “More than once a month.”

A little more than 60% of respondents answered that they use the interlibrary loan service “More than once a year.” Nearly 20% replied “More than once a month” or “More than once a week.”

Same as the previous survey, more than 40% of the respondents answered that they use the reference service at least “More than once a year.”

Over 90% of the respondents answered “Satisfied” or “Fairly satisfied,” and this is almost the same percentage as the previous survey.

Figure 11: User satisfaction degree with use of the NDL in general

Figure 12 shows the correlations between the user satisfaction and the needs for improvement on each service element of the “Website,” “NDL-OPAC,” “Copying service” and “Reference service,” as well as “Collection” of the NDL. Though “Days to receive answer” of the reference service was placed in the lower-right area in the previous survey, the user satisfaction degree has risen and the need for improvement has fallen this year, and thus removed from the lower-right area.

As with the result of the NDL website survey, service elements with a low degree of satisfaction and high need for improvement are “Easy to find information you need” of the NDL website, “User-friendliness” and “Data processing time of new publications” of the NDL-OPAC, “Speed of delivery” and “Fees” of the Copying service, and “Collection of foreign publications.” We will continue our efforts to improve these services.

Figure 12: Analysis of user satisfaction degree and need for improvement [Library survey]

* The “user satisfaction degree” is calculated as follows: specify each answer as “satisfied”=100 points, “fairly satisfied”=50 points, “not very satisfied”=minus 50 points, “dissatisfied”=minus 100 points, and “No answer” =0 point; and multiply the points by the response rate of each answer; and then, sum them up.
“Need for improvement rate” of each service element is the ratio of respondents who hope to see improvement in the element among all respondents. Separator lines on each axis show the average value of all elements.
