Seeking Michigan now has County Research Guides for 26 of Michigan's 83 counties available on their website. The counties included are:
Grand Traverse County
St. Clair County
Keep in mind that these are guides to the records you can locate for these counties. If there are specific records you are looking for I recommend calling the repository to confirm they have them for the years you are researching before you plan a trip to view them. When examining the Kalamazoo guide I noticed that a few of the years were slightly off from what I found in the actual records located at the WMU Archives.
