I think the way events transpired was that in the late 50s were published (1) the journals or proceedings of the Continental Congress and (2) the letters of all the Congressmen that they sent in this period. These were large books and each was a multi-volume series, so there was considerable information, more than just about anyone could handle. As a consequence, two books were written that present the main threads and highlights. These very well may have been written by the compilers or directors of the above projects. The book about the journals was by Lynn Montross and this book is based on the letters. But I believe both books, each still quite long, use the other source to supplement and round out their presentations. But it means that the first book is more about what happened and the second book is more about what the delegates were thinking about what happened. Neither one is superior to the other and really, to get a good picture, one should read both books, and even then, the picture remains incomplete. One should also read, probably, to fully understand the Continental Congress, some letter collections and some specialized studies on topics such as their finances, the war and foreign relations, and some biographies of the more prominent delegates. But this book makes for an excellent start, although much compressed from the source material and probably still too long and dry for many. ( )
