Seven Authors of Crawfordsville, Indiana by Russo and Sullivan has extensive bibliographies of Will and Maurice Thompson. Over the years I've used it as my basic tool for locating articles by both Will and Maurice. It is the bible for Thompson collectors.
When I began finding articles and such "not" noted in Seven Authors, I listed all the corrections, additions and deletions in a file.
I still find stuff occasionally not in Russo and Sullivan and update accordingly.
It may be of some help to other Thompson collectors so I copied it here.
