Are we always supposed to abbreviate Junior as Jr. or only when that abbreviation is part of the usage?
RDA 184.108.40.206.5 says to record the term (example is Jr.) and B2 says to record only those abbreviations that are integral parts of the name.
Junior is not in the list of Latin abbreviations. Does B2 imply that we record the usage (Junior, Jr., Jun.) in the heading?
