Do you have access to the American Iris Society's online iris register?

If so, just enter "HM 1998", for example, in the search box and you'll get every Honorable Mention winner for that year. You'll have to manually sort the TBs from all the other classes and you'll only be able to search one year/award at a time, but you will eventually find them all, at least back to 1950.
