Today I was looking up the hymns with the most instances in the database, and I was surprised to see that there was a tie for 1678;
The first one, 16th most instances overall, was "Just as I Am, without One Plea", Tied with it, 17th in the list, was "Just as I Am".
One of them has an authority page called "just_as_i_am_without_one_plea", the other one "just_as_I_am_without_one_plea". I didn't even know the system would accept a capital letter in that context.
I think it would be a good idea to remove one of these, but I don't know if there's material in the capital-I one that's missing from the lowercase-i one.
