Nearly 40% out of respondents answered that they used the NDL website “Every day” or “More than once a week.” Compared with the previous survey (FY2006), the percentage of respondents who answered that they used the NDL website “Every day” increased. The purposes are mainly “Use online catalogs” and “Request copying services.” This shows the same tendency as the previous survey.

Nearly 60% of the respondents answered that they used the copying service by postal mail “More than once a year,” “More than once a month” or “More than once a week.” This shows the same tendency as the previous survey.

More than 60% of the respondents answered “Satisfied” or “Fairly satisfied” for the degree of satisfaction with remote user services in general.

Figure 5 shows the correlations between the user satisfaction degree and the needs for improvement with various aspects of the NDL website, NDL-OPAC, copying service by postal mail and library collection. The sphere on the lower right-hand side in the figure represents the elements with lower user satisfaction degree and higher needs for improvement, where changes should be made.

For “Speed of delivery” and “Fees” of the copying service, we will continue our efforts to improve the services.

Regarding the “Library collection,” this fiscal year’s survey separately included questions about domestic materials and foreign materials.

Though the “Collection of domestic publications” indicates a high degree of satisfaction, the need for improvement is also high. It shows that users have great expectations for this element. We will step up efforts to meet expectations toward the NDL, the sole legal deposit library in Japan.

The “Collection of foreign publications” indicates a low degree of satisfaction compared with other questionnaire items. The survey results show that those who know about the NDL’s exhaustive acquisition of domestic publications tend to feel dissatisfied. We received opinions that the NDL’s acquisition policy of foreign materials was not clear, and respondents did not know what to expect from the NDL.

Figure 5: Analysis of the user satisfaction degree and the need for improvement [NDL website 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.
