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

在这项研究中，我们对Natsuya Mitsuyoshi先生（1904-89）收集的大量关于图画书、儿童文学和儿童文化的手写文件（21,540项）和剪报（29,654项）进行了分类和维护。作为一名翻译、评论家和编辑，他把优秀的图画书和儿童文学带到日本。我们为绘本和儿童文学的研究者、编辑和译者构建了一个有用的数据库。虽然我们还需要继续对这些资料进行调查，但通过建立数据库，并以新的分类方法对这些资料进行重新分类，我们可以理清这些资料的全貌，同时也可以重新认识到它们真正的历史价值。

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.
