Several additional Kalamazoo area newspapers have now been digitized and can be searched at the Kalamazoo Public Library website (click here to go directly to the search page). They are listed under Miscellaneous Kalamazoo Publications. While I cannot personally verify that all issues are in the database, given the limited run of these papers I would be surprised if they weren't. The following papers are now available for perusal.
Kalamazoo Advocate: Dec. 30, 1921 to Jun. 30, 1922
Kalamazoo Evening News: Apr. 1, 1898 to Mar. 20, 1900
Kalamazoo Evening Press: Feb. 9, 1909 to May 13, 1911
Kalamazoo Star: Oct. 9, 1921 to Dec. 31, 1921
The People: Mar. 7, 1918 to Jun. 8, 1922
Trench & Camp (Fort Custer): Oct. 22, 1917 to Nov. 14, 1918
Publication dates come from the KPL website.
I want to thank the Kalamazoo Public Library for all they do. In this age of belt-tightening the fact that they continue to devote staff and money to promoting Kalamazoo history (and making it available online) speaks to their commitment to the community.
