Prof. IKEGAMI Jirō (1920-2011 ; Professor Emeritus, Hokkaido University) is a linguist who conducted extensive studies on northern languages from the 1940s to the 2000s. He made remarkable contributions especially to the study of the Tungusic languages. Many of his published works are descriptive studies on Manchu and Uilta (formerly known as Orok) among the Tungusic languages. Hokkaido Museum of Northern Peoples has a collection of Prof. IKEGAMI’s former library materials, donated by his bereaved family. This collection is called Ikegami Bunko. The present article provides a list of all 286 sound materials in the Ikegami Bunko that he used in his research and studies. This list is not intended to present the audio contents recorded on each medium, but rather the (often handwritten) entries on the cases and labels. When the contents seem to be related to Prof. IKEGAMI’s publications and/or his notebooks, some references have been added so that they can be checked against them. The list of all 158 notebooks in the Ikegami Bunko was provided by the present author as a report “Prof. IKEGAMI Jirō’s Notebooks in the Collection of Hokkaido Museum of Northern Peoples (a List with References)” (Bulletin of the Hokkaido Museum of Northern Peoples 31, pp.85-115. 2022).
