The purpose of this paper is to examine the impact of library holdings on used book markets. The samples of this study are 234 books categorized as "shinsho" in Japan’s publishing industry. They are low-priced and small-sized editions introducing various academic topics. Of each sample, we investigated the used price in three online used bookstores, the bestseller ranking on Amazon.co.jp, the number of used book suppliers in Amazon.co.jp marketplace, the number of holdings of public libraries and the number of academic libraries possessing the samples in Japan. The period of collecting data is from December 2016 to February 2017. As a result of multiple regression analysis, we found the prices influenced by the rankings and the number of suppliers, and almost all library holdings have on small positive effect on the prices. However, only a few highly demanded books may decrease their prices due to library holdings.

In this study, I described about English Extensive Reading (EER) in Japanese secondary education. EER is one of the methods of English learning. The goal of this paper is to examine the characteristics and challenges of EER, and give consideration to a meaningful utilization of the school library in collaboration with the English teachers and the teacher librarian.

This paper is a bibliographic survey. It compares the principles by Day, Richard R. and Bamford, Julian and that of Sakai, Kunihide. Then it organized the thesis articles of EER practice in Japanese secondary schools in chronicle order.

As a result, in Japan, the principles by Sakai had a very strong effect on the practice of EER but it doesn’t mention the aspects on guidance to students. Sakai doesn’t state anything on the importance of choosing books by students.

Teaching English as a subject is mandatory, therefore teachers involved in EER programs must know how to guide students when reading books in their second language. Therefore it is important for the teacher librarian to collaborate with the English teachers and support students with reading and learning through EER in the school library.

Providing teachers with useful class materials is one of the important forms of supporting teachers by school librarians. To reveal what kind of materials is provided for what kind of classes in what ways, in this study, we analyse a wide range of school librarians’ practices. We first qualitatively investigated 279 existing reports of the reference practices and constructed a typology of elements which constitute the practices. Our typology can be used as a reference point for making consultation with teachers, selecting appropriate materials, and effectively providing them for classes. We also quantitatively explored the characteristics of the provided books from the viewpoints of the subject knowledge (Nippon Decimal Classification: NDC), the information freshness (elapsed years from publication) and the amount of information (number of pages). The statistics show that (1) school subjects are loosely related to NDC, while books in the various categories are used for each class, (2) books published within 10 years are likely to be selected, while some discrepancies are observed according to the school subjects, and (3) the number of book pages differs greatly between the elementary schools and the junior high schools.
