I’d like to mention another ‘not to miss’ repository in northwest Indiana. The Indiana Room at the Gary Public Library. The Indiana Room is a room constructed of cubicle walls on the second floor of the library. There are hundreds of books, yearbooks, microfilm of the Gary Post-Tribune newspaper, maps, photographs, and more. There are also stacks of boxes and books and news clippings. I have to wonder if it is all indexed.
The room has a few filing cabinets that hold index cards (slips of paper) indexing people, events and things from pre-1940 Gary Post-Tribune newspapers making it easier to locate information for the papers then.
One thing to note is the Gary Public Library system is talking about closing one or two branches, the main library where the Indiana Room is held, is one of those due to be shut down. I have not heard where this collection is going. I hope it ends up in another library or at the Indiana University Calumet Archives. There are so many valuable resources there.
Please contact me if you need research done in the Gary, Indiana, area.
