Card catalogue from the Suomi Koti library.

Suomi Koti of Thunder Bay is a seniors' residence in Thunder Bay. The organization was founded in 1984; the building, consisting of 60 apartment units, was opened in 1988. Suomi Koti was developed to meet the needs of Finnish-Canadian seniors

The library was built from donations and purchases by residents over the years. It held titles in Finnish and in English; the Finnish-language materials were often published in and brought from Finland and were difficult to access through Canadian libraries or booksellers. This library reflected a body of reading material of Finnish-speaking people in Thunder Bay in the later part of the twentieth century.

In 2025, the library collections were weeded significantly to make room for new furniture and better meet the needs of current residents. Some titles were donated to Lakehead University Library at this time. The Finnish-language card catalogue has been acquired by the Archives to preserve a record of the library's former collections and how it reflected the culture of its users.
