Sesso/um(s) common database
This isn't my family.SISSOM is.And, yes, we do get confused.I have what I can safely ID as the largest collection of the latter at http://www.dfc.cchttp://www.dfc.cc, and I'd invite all to visit and perhaps find something that would help.
I have plenty of disk space so I would further suggest that a common d/b be established for the above variants so a researcher could examine and compare at a single site the common confusing elements.I am averaging over 125/hits/day.May I hear from you?
