The following links are to periodical literature which is relevant, in various ways, to the study of the early American Republic.  The records of the Congress are very well represented for the period.  There are a number of magazines of the period, as well as some earlier English periodicals, showing some of the stream of ideas that formed the mindset of the early Republic.
