This study conducted a web information survey and interviews with two public librarians. It analyzed the types and characteristics of public library services for children in Japan implemented as countermeasures against COVID-19 during its first wave from January to May 2020 and the process of realizing the new services and librarians' perceptions. First, the web survey results indicated that the services could be classified into three types: web-based, such as online resource guides and original video; on-paper reading materials, such as book lists, library grab/lucky bags containing recommended books, home delivery, group lending; and interactive services. Next, the interview survey results revealed librarians' frustration that they could not provide services. Expectations and encouragement of local government officials and colleagues in the library sector motivated service realization. Ultimately, experienced and novice staff collaborated to develop the new services.

This research proposes a terminology size estimation test that estimates the number of technical terms known by an individual as a convenient method of measuring the amount of knowledge of the individual in a specialized field. This paper reports on the development and evaluation of the terminology size estimation test targeting the field of Library and Information Science. To develop the test, we created three test sets of 50 technical terms each, designed an estimation algorithm, and developed a web application based on previous research on vocabulary size estimation using word familiarity. For the evaluation of the test, two experiments were conducted with 81 participants to evaluate the usefulness of the test. The evaluation experiments showed that the test had a certain degree of reliability and validity and was useful as a method of measuring the amount of knowledge. The convenience of the test was also confirmed by the fact that the average response time for a test set was 2.61 minutes. It is expected that students will utilize this test to measure their amount of knowledge and to assess their level of learning achievements.

This paper reports the results of 1) a questionnaire survey of 272 kiyos and 2) complementary indepth interviews with the editors of 11 kiyos. We distinguish kiyos, or bulletins, published by universities, research institutions, and museums, etc. in Japan, from gakkaishi, which are published by academic associations. Of the 97 kiyos that responded to our questionnaire, nearly 90 percent are published with budget from the publishing institution, about 70 percent are published both in print and electronic forms, and roughly 80 percent of the electronic versions are available on institutional repositories. Approximately 80 percent of the kiyos face challenges such as attracting submissions, managing editorial workload, and maintaining reputation. About 60 percent seek external support, including for securing reviewers and publicity. The challenges that kiyos face and the external support they seek varies depending on the nature of the kiyo.
