The author developed a method to identify user tasks and data elements that support user tasks of Chinese classics users based on the results of interviews of their research activities. After examining the domain model, the author tried two methods: a method of extracting data elements from the use cases reported in the previous paper, and another method of assigning user tasks and data elements to each researcher's statement during interviews, which were divided by semantic content. In both methods, data elements were mapped to user tasks in three groups: purpose (elements needed), means (elements used), and results (elements obtained). Although both methods can identify user tasks, the latter provided more detailed data elements. The results of this study can be used to select data elements should be recorded by cataloging agencies, and to evaluate Chinese classics cataloging data from the perspective of supporting user tasks.

　To support teaching material provision by school librarians, we have proposed and developed a collaboration sheet that is designed to facilitate information sharing between school librarians and teachers. To achieve coverage, granularity, usefulness, and ease of use in a balanced manner, we incrementally developed the sheet. Based on previous findings, we first created a systematic set of items to be specified for sharing information on the class to be supported, materials to be curated, and ways to provide the materials in the class. Our sheet was implemented as a web-based form with functions to support users' input. A questionnaire study targeting school librarians verified the coverage and usefulness of the items and drew their qualitative feedback, which helped us refine the sheet. Finally, we conducted a user study in which teachers used the sheet while assuming a class that makes use of a school library. The results revealed that the use of our sheet facilitated the sharing of information necessary for collaboration between librarians and teachers. Considering the responses of a usability evaluation questionnaire obtained from the teachers, we selected the items tailored for teachers, to further improve the ease of use. The developed collaboration sheet is available online.
