Basic Research for the study and publication of materials in the collection of Mr. Natsuya Mitsuyoshi

在本研究中，我们对三代夏谷先生(1904年-)收集的大量关于绘本、儿童文学和儿童文化的手写文献(21,540条)和剪报(29,654条)进行了分类和保存。作为一名翻译家、评论家和编辑，他把优秀的绘本和儿童文学带到了日本。我们建立了一个有用的数据库，供绘本和儿童文学的研究人员、编辑和翻译人员使用。虽然我们还需要继续对资料进行调查，但通过建立数据库，并按照新的分类方法对材料进行重新分类，我们可以澄清收集的全貌，同时我们可以重新认识其真正的历史价值。

In this research, we classified and maintained an extensive volume of handwritten documents (21,540 items) and newspaper clippings (29,654 items) about picture books, children's literature and children's culture, collected by Mr. Natsuya Mitsuyoshi (1904-89). As a translator, a reviewer and an editor, he brought superior picture books and children's literature to Japan. We constructed a useful database for researcher, editor and translator of picture books and children's literature. Though we need to continue the investigation of the data, by building a database and re-classifying the materials under new categorization method, we could clarify the whole picture of the collection, and, at the same time, we could re-acknowledge its true historical value.
