I am truly appreciative of the sourcing on the profile, so many people seem to move fast and just not get to real sources, even though they should. Way to go, Robert!
As you will find, there seem to be slight variances in "style" although suggested styles remain uniform. Personally, by habit, I create a "bullet" before each source and separate the sources by a space, thus making the sources more legible. I don't add numbers to each source although my early profiles had them...finding that numbers require a lot of time reordering when new sources are added.
"familysource.org" is my go-to place for sources, as it's free, and fairly thorough for its entry of primary sources. Also appreciate that any of us can "click through" to see its citations without having a paid membership.Even years after entry, I may want to know the ages of all household members, if instance and the names of extra people who were present at the census may take on meaning to me as I discover extra "facts" about their presence on the day of the census.
Great job, thanks for being a super "cousin" to all of us!
