Every row is mapped onto the same trade / signing / release vocabulary the modern feed uses, with the era’s own type description kept on each row. Club names are the names of the day (the Boston Braves years, the Brooklyn Dodgers years), and each links to the franchise it is today. Some dates are only partially known or flagged approximate by the source; they are shown exactly as published, never completed to a fake precise day.
