Hello, I'm curious what the correct approach is for dealing with multiple 
entries in the browse and facet lists, when the difference is just the ending 
period/full stop.

For example, Some of the records have
=100 1\$aAdler-Olsen, Jussi,$eauthor.
And some have
=100 1\$aAdler-Olsen, Jussi.

This results in two facet lines and two browse lines for the same author.

Is the correct approach to normalize the data?

Or would an index normalizer be appropriate here, something to remove periods 
when they are not preceded by a space and a single capital letter?
Something like "r/([^ ][^A-Z])(\.)$/$1/"
